I agree with you man! I’m often using specter in battles, particularly low mana cap battles he wreaks havoc! I’ve got one level 3 and almost a level 2 on my alt account but I definitely plan on grabbing one more to get it up to level 2.
Using it in slow hits first battles usually works well, they get good debuffs for a while and it eventually dies from reflect or something but does a good job of weakening them!
