Spellthief's issues are tied, directly, to being able to steal spells that require no stats whatsoever. (Malmelo, Death Knighting, Sanctuary, etc...)

Hexer makes this build fucktupled worse because you can give yourself a ton of +CRIT from a passive. As well as give people interference rather readily.

Black bubble negates crit evade if they stand in it (making it easier to crit them with the lightning crystal rose), the passives that restore FP on a basic attack hit.. etc.. etc... etc.

All around, Hexer just makes this build scarier because there is no wind up prep time. They just fuck you in the ass after death knighting is started. Of course, this does half-revolve around the fact that the person has to Death Knighting, which is increasingly frustrating to deal with and has been a major source of balance issues in the past. +10 (or +12 in this case) to all stats for a large number of turns + fallcall for 1.5x extra damage on fear is kind of obscene. It's obvious that it isn't really a skill that is meant to be used with a mage class (since practically none of the magic classes give fear as an affliction and that falls, mostly, to basic attackers).
