Level 1 of Rush Attack and Whirlwind are almost essential for a melee warrior, but neither would be my first choice for boosting after that. Level 1 of Mana Leech is handy. I also left Life Leech at level 1, but wouldn't have ben adverse to boosting that if I had started running into serious problems.

Mana Efficiency helps after you get your creature (level 5 cuts mana usage in half), especially if you want to start using level 1 of the healing spell rather than postions. Bleed is probably the best damage bonus (I brought it up to level 10).

Character Optimization

The skill section in the walkthrough has a description and comments for each of the skills/spells.


Once you get the battle tower, half way through the game, you will have easy access to gems / ore / plants / herbs. If they are not needed for a potion or enchantment you would use, then you can sell them.
You can unlearn all your skills in the battle tower, and re-distribute you skill points, so you don't have to worry too much about making mistakes.
