I have just played through as a servile as well, but i didn't use creations. Once i got my resistances up to 120% and over, I was a tank, or a turtle mage. It worked really well, and breezed through many areas. I was pretty much invincible, but towards the end of the game when pods were low, some of the fights were tended towards stalemate slogathons, especially the one with krykk! And I didn't even get any exp. from killing him!
I used the sunstone belt which is good, and hugely underrated, combined with the special fire shaping greaves, 20% resistances in fire, cold, and magic, it really helps cut the damage down.
One of the dragons dropped a scale at greyghost gates, which doesn't seem to be on the ingredient list, maybe I was lucky?
I think i need an online geneforge unreal tournament now, with my beefy guy; or just some extra sick scenario's, to help stave off game completion blues!
