@SteamUser:
Heh. The assassin class starts with 5 strength, which explains the abysmal to-hit for him.
No. Daggers, bows, crossbows, and spears use DEX as their to-hit stat. Staves use INT as their to-hit stat. I've taken a rogue to level 10 and he hit just fine with only 5 STR.
As Stabbey said, enchanter is a crowd controller- air/water. However, the stuns from Blitzbolt just never seem to land; perhaps 1 in 4 would land, and when there's a 4 round cooldown on it.... that's just not very effective. I don't know if that's a function of being underlevelled, whether the undead are particularly resistant to stun, or what, but it just hasn't been working for me.
The stun chance is like 35 or 45% on a dry target, I think it increases on a wet target, and if you electrify a puddle they're standing in, it's pretty much a guaranteed stun.
D'ya think to-hit is partly based off level? That might explain it somewhat...
I don't know for sure, but I imagine that's certainly part of it.
