For a melee I like almost all points in her weapon - well before the end she hits 10 in death hits.

For a mage I like hammer (as noted above - it is a great spell, paralyzing as well as damaging the enemy) and one mass damage spell like lightning storm.

LOL no one has mentioned the obvious unless I missed it. Cash is fairly easy to get with 1.44 so there is no reason to worry about what skills you may need in a later part of the game. Take what is useful at the moment and unlearn it when you need the points for something better.

Reality is for those who cannot cope with fantasy. Fortunately, I can cope quite well.
