Prioritise enchants that grant SP, pref. Haste also if you're swinging with Arcane.
Head - Kirin Tor Head Enchant (achieved w/ rep).
Shoulders - Sons of Hodir Shoulder Enchant (+Sp/+Crit)(also achieved w/ rep).
Cloak - Lightweave Embroidery (if tailor) // +23 Haste
Chest - +10 All Stats
Wrist - +30 SP (believe there's a better one available if you're a leatherworker).
Gloves - Hyperspeed Accelerators (if engineer) // +28 SP
Belt - Eternal Belt Buckle (not an enchant, but something a lot of newbies gloss over).
Legs - +SP/Spirit Spellthread (obtained from tailors or AH).
Boots - Tuskarr's Vitality (for movement increase) // Icewalker (for +Hit, if needed).
Rings - +SP (only available if enchanter)
Weapon - Black Magic // +63 SP
What spec are you playing // intending to play as?
Your meta gem should be a Chaotic Skyflare Diamond
for the bonus +Crit damage, as this stacks with several other mechanics and effects. Be sure to have at least two blue gems (or gems that count as blue) equipped to activate it. Generally, you gem pure SP in red sockets, SP/Haste in yellow and SP/Spirit in blue (use the bigger +SP gems in reds if you're a jewelcrafter).
Your spec may differ these choices slightly.
