LTS asked what spells restore lost limbs etc...
Howland Troll warts does not work.Regeneration cast from a spell, scroll, or plot-specific device works.
Greater Restoration and Heal does not work.
I have in many cases, have confirmed reports from DM's that greater restoration, does indeed work. I assisted a character regain his armor by having a DM possess Grizabella and cast greater restoration upon said character and the Spell Failure went away and the DM put in a word for him to have his arm back on the model.
Is there going to be a final ruling on what spells and what does not?
