Some observations regarding skills.

Fireball, horribly poor, because you end burning yourself with it.

Lightning storm, the UBER masskilling spell, max it to 10 points. None of the other attack spells compare to it.

Elder Fire, seems good, but lightning storm hits targets much better.

Ive noticed that a lot of things seems to be pretty weak to crushing, crushing is especially good for act 1. And i think in later acts its still good. Slashing seems to be whats most resisted by critters.

imo you have far too few skillpoints in this game that follows the same skillpoint model as divdiv, where skills could go up to 5 ranks, and you could find skillbooks for many things, or being taught. Here, to max a single weapon proficiency, you need a staggering 50 pts.
