I also asked in my previous topic, and finally found best method based on my character.
fighter, mage, deathlord, level 32.
1. fire ward is a must, then combine it with blast nova (v usefull if other creatures<poisoned especially> are around), iceball and ice nova also good.
2. combo weapons of no-dachi and kama flame or winter dagger.
I spent 2 fire ward, 2 blast nova, 1 ice nova. Occasionally hide behind tree.
Still figuring out how to lure the last dragon (in egg's mission) to came down from the hill.
Any ideas what spell can be produced from her teeth
