Wands of healing will work on non-living monsters like iron golems and orbs of fire. Since undead players can use wands of healing on themselves I suppose that for parity they have to work on monster undead, but I would think that for truly non-living it would work. Then again, that would mean that wands of healing wouldn't work for player while in statue form...
A "not" missing in "...for the truly non-living it would work"?
Moving to FRs.
