Avoiding the really bad outcomes, like Foul Spawn, feeblemind, and death?

Re: Luck, does it help for Transformation ritual?
 

Well, twiceborn cannot help you.

There are several possible results:

One is that you turn into some critter, magical or otherwise. You retain the twiceborn enchantment.

Two is that you turn into a feebleminded foul spawn. You retain the twiceborn enchantment.

Three is you die. Your twiceborn enchantment triggers. You return, with experience and increased death magic. It does you little good, since you are now a Blind, Weakened, Crippled, Mute, and Feebleminded Wight Mage. (Your afflictions may vary)

By the way, Edi, I've detected what is most likely a bug with transformation.
