Coming down to the end of this god awful system, thankfully! Corruption is bad enough, but the vendor rotation concept is laughably bad. Bring on SL!
As of right now there is no Versatile III available from the corruption vendor.The current available corruptions as of 12/09 match up with what you suggest is available from October 6th.Ineffable Truth I - 3300Honed Mind I - 4125Strikethrough II - 4125Masterful II - 4125Expedient III - 5000Twisted Appendage III - 13200
Imo in a last week before pre-patch they should make corruption cost 0 and make them all available at once. Just go nuts, have some fun, tryout things you always wanted but were too lazy to farm for.
Glad Shadowlands is coming soon, 8.3 was such a trash patch, I think I hated it more than the rest of BFA.
