I've been playing on Veteran with upscaling (consensus on that working appears mixed but I agree with the idea), at about level 7 right now, and I have been having a similar issue with debuff and damage spells on my wizard. In most engagements I have found myself looking through my spell choices for Aloth, I have all these great looking debuffs (confusion, expose vulnerabilities, the slowing one) but when I click on any of them and hover them over the enemies, they all have % to hit in the 30's and 40's. At that point I figure the spell isn't even worth the cast time and end up having my wizard shooting that frost warbow with the multiple projectiles for the whole fight. Am I doing the wizard thing wrong or is this just the growing pains of lower levels? I really like the idea of the wizard laying down all these debuffs and area control spells to support the physical damage characters (never been a fan of straight blaster wizards since dnd) and would like to make it work.

I'm giving this build a spin for my first playthrough (Hard), I liked the idea I saw in another thread about having both Kana and my PC built this way. Would anyone be able to recommend some suitable midgame weapons for this build? I've got 2 characters using it, and I don't really have weapons that seem right for them them. I gave my PC Hearth Harvest because Fire+DR Reduction+Deflection seemed like a good combo for a tank with a fire theme, but I get the feeling that I'm reaching the end of it's useful lifespan. I don't think I have developed a good head for the gear in this game yet, reading this forum, I see I have already overlooked some pretty good items, so I would appreciate any insights.
