Ok, IIRC there are a few useful ones:
Curse: Lowers resistances, Can be stacked and is not resisted. The animation effect 'stuns' the monster too. Almost too easy.
Alchemy: 1 point to stop the need to constanly buy potions.
Poison weapon: Massacre the orcs! Poison skin is cool too.
Deadly Gift: Scorps are cheese, use for tricky situations.
Identify has its uses, particularly if you want a good weapon without to much reloading. Save on gold for I.D. purposes too.
Don't bother with necroshift, it stinks. <img src="/ubbthreads/images/graemlins/ouch.gif" alt="" />
Wisdom: there has been debate on this. Apparently its not worth it. I like the faster levelling myself.
Magic Barrier: not worth it unless you badly need resists.
Aura of Command: one point is good if you have resurrect or scorps. Crashes have occurred with a higher number of 'minions' though.
That's about it I reckon. Have fun! <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
