Thanks.
I do think that Witchcraft needs more damaging spells, though. There are only 2 in the entire school, with a 12+ level gap between them. Even Water has more damage spells, and Water has healing, a con buff, one of the best group-friendly synergies in the game (Rain + Blitzbolt/Lightning Strike/Chain Lightning, laugh, murder everything), a summon and debuffs.
Unless the devs really want Witchcraft to be used only for Oath of Desecration and maybe the summons (which is pathetically weak compared to the fire summon, the spider and the ice summon), it's kind of difficult to play it as anything other than "give the melee damage buffs and watch the bodies fly". The short range of the debuffs make it unfeasible as a debuff specialist, since that means your wizard has to actually get up close with the mobs. Hell, Rain trivializes Witchcraft debuffs in the entire fire section of the cemetery, and trying to debuff a boss is suicide.
Even worse is that the only ranged damage dealing witchcraft spell in the game so far is garbage compared to its elemental counterparts, because the undead don't bleed and undead are 75% of Cyseal's enemies. I'm not even sure why Death Punch is part of Witchcraft, it's basically punching something really hard.
