This is a very decent spell regardless of your spec; though being Arcane certainly makes this thing that much better.

It excels at dealing exceptionally high damage for a very low mana cost; anything beyond the first cast is, essentially, a waste of mana - unless you're trying to quickly burst down an opponent regardless of how much mana you're spending.

The best way to use this is to alternate your casting.

This is easy for PVE: start off with a Frostbolt or Slow, then cast Arcane Blast, then Arcane Missiles. When Arcane Missiles wears off, cast another Frostbolt or Frost Nova and move or Blink away. Cast Ice Lance (if you learned it and have 5 points in Ice Shards) until enemy is dead. If the enemy isn't dead by the time the freeze effect breaks, cast Arcane Blast again and finish them off. Hopefully they'll be dead by then. (Note: Recast Frostbolt/Slow as needed.)

I can't describe a proper method for PVP, as tactics change for each class and I don't have the kind of time to go through each one! However, a variation of the above method works well against some classes.

Ever since i saw the new talents and spells in BC i wanted to try an arcane build with arcane blast/arcane missles. I specced arcane @ lvl 64 and been trying arcane ever since (i'm 70 now for a while). After long time tests my conclusion is this :
- arcane build is still useless for pve/raid
I have 10k+ mana self buffed and ~13k raid buffed. ~1k spell dmg raid buffed. I figured the best way to efficiently use arcane spec is to alternate arcane blast and arcane missles. It works pretty well tbh, i never get more than 1 debuff which is acceptable. The only issue which is major is that i still run out of mana, even with a pretty high mana pool and arcane meditation, and raid mana regen ...
Considering the fact that many raid fights last very long (even close or over 10 minutes) an arcane mage can't keep up dps over 10 minutes. At least i can't.
The sad thing is that T5 buffs/debuffs even more arcane blast :<
Well these are my personal opinnions and you may prove wrong but me, i'm gonna try an arcane/frost spec.

Well I currently spec 58/0/3(lower ice.fire spell cost.)
And I I found good way to reduce mana cost, and still keep damage.
AB+AB(gives 2 debuffs)+Scroch+FBall+FBall then repeat

When Clearcast Proc's Ap+tinkets Free AMat 1k-1.2k per hit, and 1.7k-1.9k crits, the best I had so far is 5x2.1k over 10k damage for free.
you can look at my stats on armour to check my arcane speced gear. Maddy - Ravencrest.

thx mynea was just thinking about that ;D

Comment by 31067

with +547 arc spell dmg at lvl 70 my mage hits around 1.1K non-crit with Arcane blast and twice that with spell power when criting - something he does quite often with 30% + 6% (from talent) spellcrit.

one of the best mage spells atm for raid bosses and even instance bosses

Comment by Dorothea

Calculations aside, cause i cant care to much. This spell proved very useful if used correctly.

Example is the fight against Alar, fire immune boss for those who dident know. Anywho, fire is and allways will be the best damage spec (10/48/3) for raiding against almost all bosses and encounters in the game.

Anywho, start off with 2 casts of arc blast, and while the debuff is fading, use frost bolts, cast arcane missiles when clearcast has procced.

Even though your not solely using arc blast, it will deal the majority of your damage as clearcast is random.

Yes as a fire specced mage against a boss like alar, you will not top the dmg meters, but you will do a reasonable enough amount against this somewhat easy boss to save yourself the need to spec frost.

Comment by 112286

Not to be brat or anything, but why does so many do calculations on the debuff for the 4th and 5th cast when the skill note says that the "buff/debuff" only stacks 3 times?

Guessing it was changed at some point but I'm imagening that this could be shot off more than 3 times in a row to get a very high dps for short fights, since it's got half the casting time compared to imp. frostbolt/fireball.

Please correct me if I'm wrong.

Comment by Xhurin

Being a 40/0/21 spec, Draining 60% of my mana in 2 mins is not unheard of if I really want to:

People say this spec takes way too much mana, which may be true, but the DPS is insane.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1.5 Sec cast - 30% from Bloodlust - 20% from Icy Veins - 15% from Haste Rating*
+ 30% Mana cost + 20% Mana Cost from T5 2set Bonus + the 225% Mana cost = OOM

BUT: +30% Damage From AP + 20% Damage from T5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Without the 2 Piece T5 Bonus, and gear not extreamly good, Pre 2.4 Badge Gear, Spellfire, I can Peak at about 1400 DPS, averaging out about 1k Even. With the changes to Evoc Being 60% of your mana (Switching to an "Of Int" MH/OH with +30int chant gives you an even higher boost), The change to the Highest mana gem having 3 Charges, and a Pot cooldown, I dont have too big of a mana problem.

Also this build Should use Mage Armor instead of Molten for the Extra Mana Regen, Most mages will have 20-25%ish Crit chance Buffed without Molten. An Extra 6% from Talents Puts you at 26-31%.

Stack 3 Charges > Macro PoM, AP, IV, Trink, Mana Gem (with 2 Piece T5 you will Drain your mana Far enough to use it), Etc all together > Go Nuts... Evocate > Cold Snap > Stack 3 Charges > IV and Go nuts again. If you run out of mana, Cast a Down Ranked Spell (I use R1 Frostbolt) to Proc Clearcasting, or just Wait till the Debuff Wears Off and Hit AB Again.

With salv and the Amazing 40% reduced threat Talents you should have, Most tanks will be able to hold the TPS.

I Havent Tried This Past T4 Content, but Have a Mage in my Guild Who has had it Post T5 Content, and it has Worked So far. So it Is a Viable Spec.

*Dont Knock it. Haste Rating FTW if you have a healthy Hit Cap and +Dam, and Yes i have seen 15% Spell haste.

Edit: Spelling

Comment by veno3

This spell is getting reworked in WotLK. Quote from current Beta patchnotes:

Arcane Blast effect duration reduced to 3 seconds, now increases damage by 15/30/45% instead of reducing cast time.

Comment by 164017

Ok, I am well aware that this is a pretty unusual way of using AB, and that there are IMBA mages who cant handle the mana drain.
But, if you are a little carefull and give it some practice it is possible to spam arcane blast for well over 10 mins and only throw in an AM a little now and then. Many bosses have a 10 min enrage timer, that's why I say 10 mins. I kept it up for 18 mins on Lurker on my guilds 1st down, and ended up with half my mana left (yeah, noobish done, should have drained it a little more)

This is how it works (mainly for 25 mans, be more carefull in Kara and ZA):

Spam AB
Pop your mana gem as soon as it fills your mana to 95-98% (just so you wont waste one single point of mana)
Spam AB
Use one AM and give it bout 0.5 sec before you
Spam AB
Pop your next mana gem asap
Spam AB, throw in an occational AM when you feel you have to go down in mana drain.
Evocation when your just below 40% mana (if it's possible at that time, be carefull at some bosses it aggroes if they for example reset threat or spawn adds)
Keep repeating this, with enough practice and right amount of int and spirit (yeah SPIRIT, an arcane mage use mage armor, so we have 60% mana regen while casting -compare to a holy priests 30%)

Personally I am currently raiding on an arcane / icy veins specc and it has brought me the higest dps, way higer than fire / icy veins and slightly higer than arcane / pyro.
I use PoM for getting the AB (de)buff back up if I should lose it, else it's there untouched.. To throw a fireball or frostbolt with it would mainly be a waste of a GCD imo.

Wanna end with saying that I am well aware of that many ppl will laugh at me and think or even write here that I am a noob. But if so it's not my fault it's hard to manage the arcane mana, and so far I have not once gone OOM because of this rotation.

And for those of ya who read this and wanna try it:
GOOD LUCK, and remember to bring a few mana pots aswell. the more mana you can spend, the more dmg you can do.:))

Edit: posting to fast here.. a few things I forgot to mention:
Timing your AMs on a clearcast for the extra crit is a good advice, but I wouldnt bother too much about it if I didnt have time to pay attention to clearcasts. Thinking too much about it, will lower the dps as much as the dmg you win from the crits. But aim for AMs on clearcast when you know your spells and the bosses.

Also, I have found bout 10k unbuffed (not even arc int on) mana being very usefull for this specc/rotation.
And, 10k unbuffed was what I had in spellfire/spellstrike, a couple kara/HC epic and s1 Gladiator Staff, Vinicator's Silk Cuffs and rings and trinks q and rep rewards. So, 10k mana is easily obtainable for an arcane mage.
Below these gears I would stick to an arcane / scorch specc. Gonna be a higer dps than a fire / icy veins at this gear lvl anyways, and the absolute best dpm a mage can find.

Comment by 171449

This was changed in the latest PTR build. The spell damage increases by 15% but the mana cost goes up 300%.

No buff = 200 mana

1 buff = 800 mana

2 buffs = 1400 mana

3 buffs = (I couldn't get that high with the amount of lag on the servers but it would be 1800 mana theoretically.)

Comment by 89922

Anyone happen to know the air time on AB? Depending on that... might be swappable between ABarr and AB... just back and forth... without to much thinking, but then again it might not, as the AB would land weird.. I dunno, just a thought, I don't have an active account to test it with though.

Comment by 45315

Blizzard nerfed the mana cost increase to 200% becouse they dont want Arcane Blast to be the only spell we use, right now you can raid with only this spell. If you do Arcane Blast + Random spell then start casting Arcane Blast again, the debuff will be gone before the casting is complete and it will cost normal low mana.

Comment by 164017

have been really worried about the changes to Arcane Blast, but in the end I must say I like it.
First of all, an 150% increased mana cost on each stack would give us a lower mana use than we had untill now.
So, 200% increased on each stack doesn't seem too much of a problem to me. Not as lvl 80 anyhow.

But I'm still concerned about the dps of the spell. A 15% increase of dmg for each stack isn't really enough to weight up for the longer cast time, unless I missed something when I looked at it.
Alltho the boost to AB that we get from talents might weight up for the lost dps.
Since we'll be loosing the (de)buff as soon as we even look at something but Arcane Blast I feel that it's close to impossible to say anything for sure about the dps untill we've had some time to try it ingame, to get to know how often we'll loose the (de)buff.

The changes might be a nerf or it might be the best thing that's ever happened to the arcane specc.
Anyhow, the increased mana cost is not the end of raiding arcane mages, but if we're ending up with a much lower dps that could be the end of arcane...

Anyways, the spells and talents of 3.0.2 is tuned for lvl 80 and will work differently on a lvl 70 compared to when we hit lvl 80.

And to say that fire mages only spam fireball apart from an occational scorch was true, untill now. Instant pyroblasts? do I have to say much more. To me the fire specc finally looks fun.

Comment by 63016

Is there a reason no one see's how useful this is here?

Since Arcane Barrage has a 3 second cooldown, it fits perfectly into the rotation.

Arcane blast followed by Arcane Barrage. Rinse and repeat. Maybe an Arcane Missles here and there if you dont have to move around and you're worried about mana.

The global cooldown from arcane barrage will put you over the three seconds so you dont have to worry about mana. If your ready to down a boss or something then skip the barrage in the rotation and just stack the buff.

Arcane Barrage is a bit costly, but far less than Arcane Blast with 3 stacks.

Comment by 232933

Notice the http://www.wowhead.com/?spell=54490 talent... It makes that Arcane blast, Arcane barrage rotation even better. You just cast Arcane missiles instead of blast when the buff is on. I bet that someone with some macro skills could make spammable macro for that.

Comment by 240887

Im totaly happy with the 200% just means you have to mix it up with barrage and missiles(when it procs)

IMO the only problem is its damage coefficient atm
71.43% (+9% from talents)
80.43%

not totaly sure why this is only 80% .... even frost bolt is 81 base and 91.43 with talents,and its that way becouse of the slowing component.

IMO this spell should be a 90% ish coefficient as i agree fireball should be higher becouse of the higher cast time but i can see no reason for it to not have at least the same or higher coeffishent than FB

Comment by Envision0

Arcane Blast -> Arcane Barrage -> Arcane Blast -> Arcane Barrage
- When Missle Barrage Procs
Arcane Blast -> Arcane Barrage -> *Proc MB* Arcane Missiles -> Arcane Barrage -> Arcane Blast

Use Barrage after any spell mainly. Mana is hardly an issue for me with the Glyph of Mage Armor and Arcane Meditation. This generally puts me at 1.2 to 1.3k DPS in Kara gear.

- Also when matched with numerous mobs, and considering you have a tank that can hold decent aggro on multiple targets, I place a Mana Shield on myself and Arcane Explosion. It causes more damage than Blizzard if you're specced Arcane. The only problem is your vulnerable to AoE damage that mobs might cause. I realize it's quite mana costly to use Arcane Explosion too, but I generally rarely have mana issues. Just eat a biscuit when it's over and by the next pull you should be fine.

The only big issue I see with arcane is it's no where near as powerful AoE damage as a Fire or Frost mage. With the new Wrath dungeons there are going to be a lot of jump situations where AoE will come into play, so we'll have to see how it goes. >.<

I think we deserve an AoE Arcane Range spell =P

Comment by Sporeggar

This is a force to be reckoned with. Most people in my server underestimate it in PVP. It is very useful if you're at a hidden place considering that this spell does not leave trails unlike frostbolt and firebolt.

Comment by 71190

Probably not the smartest thing to do in raids.... but if ur looking for a big crits in PvP or whatever, go Arcane Blast x 3, Arcane Power, Arcane Missiles. =)

Comment by Mailiamah

Actually, While reading the Upcoming Mage Changes thread at elitistjerks, I found a post that broke down the best dps method for an Arcane mage. (post 3.0.8)

(Using someone elses gear for numbers)

mentalfloss@elitistjerks

Arcane Missiles: 2971 dps, this means 5942 with missile barrage. -> 14855
Arcane Blast: 2976dps -> 7440
Arcane Barrage: 3919 dps -> 5878.5

each ABar ABlast cycle has a normal dps of 3329.6 and 36% chance to proc Missile barrage, which is an increase of 2612.375 dps for 2.5 seconds.

I think it's reasonable to assume the proc between ab and abar in the cycle would be unusable because you are already casting abar, thus you only see the proc after each pairing of 2.
* - represents a missile barrage proc below.

AB ABar * AB AM ABar continue with normal dps cycle of ab abar
Total damage
7440 + 1.15*5878.5 + 7440+1.15*14855 + 5878.5 = 44600

ab abar * am ab abar continue with normal dps cycle

7440 + 1.15*5878.5 + 14855 +7440+1.15*5878.5 = 43253.7

Both are over the same time

With the first rotation, you lose out on a 20% to get another MB because it's already proc'd while you cast a ab to buff, so that buffing ab's proc is lost. This translate to an actual 16% loss on the proc as you already had 4% loss of the proc with your normal ab abar rotation. 4% being the chance both AB and ABar proc and thus the AB proc is useless

16% chance to lose out on a net increase of 6531 damage = 1045 extra damage on the second cycle due to extra proc.

It's very clear AB MB ABar is a better rotation on the proc than MB AB ABar

it seems to me, you should ALWAYS buff your proc'd Missile barrage.

From the same posting he also mentioned that it would be worthwhile to fully buff your Mbam (Missle Barrage Arcane Missles).

...if you have mana to spare, *proc* AB AB AB MB = 7440 + 8556 + 9672 + 21539.75 = 47207 over 10 seconds is better than the dps loss over the 3 possible procs that would be lost due to them being redundant.

Also, I've played an arcane mage for end game content of TBC, had to respec for leveling, and with the upcomming changes to Arcane I've specced back into it to get use to it again.
From what I've seen from 2 Naxx runs, and a Bunch of heroics Glyph of Mage armor is pointless for arcane mages (Unless your using to heavy of a burn cycle). I've found myself using more Molten armor making my Glyph of Mage uselss. Gem at each cool down. If I know the fight I can even pop a safe Evo and go right back into my burn cycle. (Using 3/3 Arcane Med and 2/3 Master of Elements)

Comment by Sunsilk

What does the new glyph for this spell do?

Comment by 187972

I haven't really tested it but does anyone know wether the stacking damage bonus applies only to the base damage of the arcane spells or the total amount (with the added coefficients, popped trinkets, etc.). Feel free to rate me down if it's a stupid question.

Comment by coldviper18

One of my favorite things about this core arcane mage spell is in PvP.(BG's and World specifically). Mages have a habit of being focus fired, since we can easily destroy people in seconds if nobody pays attention to you.

Anyway my favorite thing is that it's not a projectile. So if like me your a BG and world PvP fan, if your good at finding hiding spots where you can still be in LoS, you can literally spam the crap out of this and with the way the game is these days its gonna be hard to notice your even being hit with it, let alone figure out where since its not a projectile.

Just a nice little bonus for the spell. Being able to hide and blow people up without them knowing where. Or even notice that its happening until its too late.

Comment by Fishrule

There is a nifty rotation that you can use, when you have 2 or 3 stacks of arcane blast, depending on what your mana is, start casting arcane missiles. The buff will only cancel after the last missile hits the target, which allows you to put in an arcane barrage that will also benefit from the buff!

Arcane Blastx2--->Arcane Missiles---->Arcane Barrage

Comment by 269297

Request change: 3 stacks of A Blast will turn your next Polymorph spell into an instant cast.
(or alternatively perma-poly the enemy, whatever you think is best.)

On a more serious note;

Using Rawr to calculate my DPS, it says that a 3stack of Arc Blast spam will be doing about 900 more DPS than a 1 or 2 stack of the same spell (1 and 2 only has about 30 DPS in differance.). I suspect it might be taking into account my Illustration of the Dragonsoul, which will be giving me 200 SP at 10 stacks. Any ideas?

Comment by 258153

As your stacking up your Arcane Blast, you'll gain the 3 stacks, leading up to 600% increase in mana for your next arcane spell.

Arcane Blast will not consume the Buff -but what i did notice, was that Arcane Blast does in fact increase its base mana 600% -.-

killing Dungeon bosses, i normally would just spam Arcane Blast and when Missile Barrage proc's, Arcane Missiles.
Thats when i noticed that my Arcane Blast starts 221 mana, at the 1st cast, increases to 663, and at the 2nd cast, it increases to 1105 mana. Either this is a mistake or this spell is horrible to spam with, unless your doing your Arcane Blast (one stack) then following it up with a Arcane Barrage.

Besides the point though; "Effect stacks up to 3 times and lasts 10 sec or until any Arcane damage spell except Arcane Blast is cast."

the mana increase should not affect Arcane Blast(s), but it does -please correct this in the next patch x.x

The buff that increases arcane damage will apply for Arcane damage wands!

Hmm, it says the Arcane Blast debuff last 6 seconds, isn't it only 5 seconds now? Thats what my timers say.
It's abit sad when u got your ABx4 and getting cc'd by a boss, *pow* gone :\ But i love the dmg output<3

Comment by 101243

It's a damn shame this spell isn't available to lower levels. Without AB, arcane is a completely useless spec to try to level up as.

Comment by Elysianfield

Actually, if you didn't get Missile Barrage after the first 3 ABs, there's a 87,04% chance of getting it after the 4th one. I'd say it's worth the blindshot.

The way this is phrased isn't quite accurate. It's a misconception known, among other things, as the gamblers fallacy. There is still only a 40% chance of getting a MB proc after your fourth Arcane Blast because each cast is a distinct, independent chance to proc MB. If, for example, you toss a coin up in the air five times and it lands on heads five times, it still has a 50% chance to land on heads on the sixth toss:
H H H H H H
vs.
H H H H H T.
If this wasn't true you'd end up with contradictory statements, for example:
Suppose Alice tosses a coin five times and it lands on heads five times in a row. Bob then walks in and Alice tosses the coin to see whose the better mage. Alice fallaciously thinks that since the head has already landed on heads five times in a row it has a "higher chance" to land on tails. Bob, who hasn't seen the previous five tosses thinks that the odds are 50/50. Clearly, both can't be right. In this case Bob is right since, if we were to follow Alice's line of logic, we would have to consider not only these five tosses, but all tosses that that coin was used in. If we follow this line to its extreme, we'd find that given an infinite number of previous tosses, the odds of landing on heads is about 50% anyway.

You could correctly say that there was a 1/32 chance of getting the coin to landing on heads 5 times in a row and before you start tossing the coins you could correctly say that there is only a 1/64 chance of landing on heads 6 times in a row; however, these are all talking about groups of events. For any specific event there is a 50% chance of landing on heads.
(Hence "gamblers fallacy": the illusion that because they've had many loses gambling they are "due" for a win).

The way that this should be stated is, "There is an 87.04% chance of having MB after having casted AB four times." The distinction here is that we're looking at four events together (going from 0 casts to 4), rather than individually (going from the 3rd AB to the 4th).

Comment by SpareSimian

As a PvE frost mage I don't really understand how to use this. I've been blasting away with frost bolts on single targets, followed with ice lance if the target freezes. (Blizzard for AOE.) How do I incorporate Arcane Blast into that?

Comment by Elysianfield

Actually, dont be so analytical
he specifically said "87% after the fourth cast"
which is a compounded number, 40% x4 diminished from 0.4 in 1.0
which is dead on accurate, as he was specifically talking about 4 casts

"you have 87% to have it -AFTER- the fourth cast"

he didnt say "ON THE FOURTH CAST", which would have been wrong.

your thinking is correct, but not in his context, not even close. dont try to be an ass like that.
especially since you cant read properly.

He specifically said, "Actually, if you didn't get Missile Barrage after the first 3 ABs, there's a 87,04% chance of getting it after the 4th one." This is the same as saying, "Even If I loose the first three coin tosses at least I have a 93.75% chance of winning after the fourth toss," which is not true. There are only two events that can occur on the fourth toss, I land on heads or I land on tails - the three prior coin tosses have no bearing on this case. Likewise there are only two possibilities that can happen on the fourth cast, he can either get MB or not get MB, what happened before does not matter.

Put yet another way, it is because he already stated that the first three casts *have not procced MB* there is only a 40% chance of getting it after the fourth cast.

This is precisely why it is called the gambler's fallacy. "Oh I didn't win the first X times I played therefore there's a high chance I will have won after the next game." The game itself does not change after you have played it - and lost - several times.

Your thinking is incorrect and, in this context, not even close. If I had wanted to be an ass I would have made a syntactically unambiguous statement such as, "you are a moron," but I know how easily that could have been misconstrued as an insult, especially since some people can't read properly.

hitting 25k+ on the ptr on 1k resil

Comment by 263972

The best single burst spell pre-cata

This spell can crit well over 55k with avg. 333 iLvl gears when stacked 4x and glyphed.

Lets say a mage in 5-mans with all of the spell and damage % debuff on target + AP and somehow got full mana on 4th stack.100k crit isn't that hard to achieve IMO.

Although it would be extremely VERY inefficient spamming this, because 700% Mana cost would burn all of your mana pool in under a minute..

Comment by 633171

What?

They just ruined the arcane mage rotation..... if there were any at all..
If what was before may be called a rotation there is definately no rotation now :(
I simply don't understand how there can be any rotation when Arcane Blast only affects Arcane Blast itself, what is then the point of Arcane Missilies and Arcane Barrage?

I imagine Arcane Blast beeing the only spell cast in some fights... and even if it does work with regard to mana problems, what would the fun be? 1 button to press? like WOW, how original... -.-

In addition the whole speciality of Arcane now relies in maxing your mana and mana regeneration and minimizing mana cost of your spells, so launching this several times with 700% mana cost isn't much of a mana efficiency...

but the rotation... where is it?

Comment by ughzean

Arcane Missiles used to crit over 10K (each) for me

now they crit 4K each

sufficed to say i never use them anymore :/

i think blizz should make it with having mage armor allows you to channel arcane missles while moving for those very (move) oriented fights

because if im standing still theres only one spell im using lol

Comment by 382654

Arc Blast seems to be broken since Cata came out. maintaining 18,000 dps was not a problem before cata came out, Now I am lucky to sit on 10,000 dps. (Yes i am hit capped). Damage increase is seriously undervalued compared to the casting cost increase. I find my dps highest when i revert to the old. 5 ABla, 1MB , 1ABar rotation.

PS... I do Higher dps in my frost pvp spec in heroics.

Comment by whisperingsage

In the current PTR (4.1) they fixed the tooltip to correctly show 5% base mana cost, and lowered the cast time to 2.0 seconds. As they have not changed the cast decrease with stacks, this will lower Haste's priority with Arcane. Even without any outside haste, Blast will get down to a 1.6 cast time at 4 stacks.

Comment by SoooWhoCares

For Level 85, Patch 4.0.6:

Mana costs: | Stacks: | Damage bonus % (unglyphed): | Damage bonus % (Glyphed):
1219 | 0 | 0 | 10
3047 | 1 | 10 | 13
4876 | 2 | 20 | 26
6704 | 3 | 30 | 39
8533 | 4 | 40 | 52

-only boosts Arcane Blast damage
-each stacks reduces the cast time of the spell by 0.1 sec
-the modifier buff / debuff fades when any other arcane spell that deals damage is used
-the modifier buff / debuff can't be dispelled or stolen anymore (it's uncategorized now)

Edit: These are the mana costs for a human mage. Since the base stats of a level 1 char are a little different per race the mana costs may vary a little.

Comment by 849686

Overall damage of this spell has been reduced by 5% as of patch 4.2. This spell is the Arcane Mage's primary nuke spell and will deal a lot of damage if used correctly. Continuous casting will burn through a lot of mana but will deal fast damage.

Strategies:
Mana Conservation Phase (Evocation on cooldown):
2-3 casts then use Arcane Missiles if available or Arcane Barrage. Use Arcane Barrage more often if mana is low. Repeat. Use Molten Armor for extra crit rating. Use Mage Armor if your mana is very low. Use Frost Armor if you are taking a lot of damage.

Mana Burn Phase (Evocation is ready):
Cast only Arcane Blast. Ignore Arcane Missile procs. Use Molten Armor only. Use Arcane Power and then Mirror Image (if necessary). At 60% mana, use a mana gem and continue. This phase ends with an evocation.
- This method will use a lot of mana very fast! Best used during boss fights or when a ton of damage is needed NOW.

As of patch 4.2, the damage range appears to be 1677 to 1947 arcane damage at level 85. The values shown on the spell here don't match testing. The spell power coefficient is 1.0. On the in-game tooltip, the numbers reflect spell power added in to the base damage, times any spell multipliers (25% for Arcane Specialization and 3% for Arcane Tactics, if you have it, 28.75% total). The tooltip values don't include Mana Adept (mastery's effect).

I hope Blizzard is going to balance the values of Arcane rotation spells while working on the next expansion (I'm sure they are): Arcane Blast-only-spam gets extremely boring quickly.
What I think would be a nice change is to change AB to be more like:

Arcane Blast:

with the addiction of a talent like:

Arcane Fever:

This would provide some nice tools to keep Arcane efficient during encounters that require a lot of movement.
It would also make AM and Arcane Barrage more attractive overall and not just necessary to clear AB debuff; while nerfing AB removing the cast time reduction provided, returning to a more-like WOTLK rotation (at least in fights that do not require so much moving around), hopefully waiting for some even bigger change.

This tooltip would be both shorter and clearer if it said "...until Arcane Missiles or Arcane Barrage is cast." (You'd think Mirror Image would count as a damage spell.)

What is the name of the proc from this spell?

Edit: Never mind it's: Arcane Blast (Arcane Charge)

Comment by GoHF

For the sake of giving some perspective to those not playing the beta: in ilvl 484 pvp gear, self-buffed, fully enchanted, gemmed, with popped trinkets, flasked, potted and full procs, arcane blast has crit as high as 398k on a dummy.

That's the kind of peak burst you can expect from arcane, and more as the tiers roll by.
