The creature casts the 8th-level spell veil of undeath [necro] (SpC 229), which says, in part, that
Like an undead creature, you are damaged by cure spells and healed by inflict spells. You don’t actually gain the undead type from casting this spell.
Then the creature is the target of the 7th-level Clr spell fortunate fate [conj] (SpC 99), which says, in part, that
You surround the subject with an aura that immediately heals the creature if it is subjected to an effect that would kill it (reduce its hit points to -10 or below). When this event occurs, the fortunate fate spell intervenes by immediately triggering a heal spell upon the target.
If the creature's reduced to -10 hp or below before the expiration of the spells fortunate fate and veil of undeath, what happens?
- The creature is the subject of the spell fortunate fate's heal effect and regains hp; the spell heal is neither a cure spell nor an inflict spell, and the creature looks like a genius.
- The creature's even deader upon the spell fortunate fate's activation; the spell veil of undeath uses cure and inflict spells as shorthand for positive and negative energy, and the creature looks like an idiot.
- Your answer, if neither of the above.
