The power says:
Corpse Body. Your body is a corpse. This means
that you cannot recover from consequences
with time, because your body does not regenerate. Any physical consequences you suffer
are permanent until you take some kind of
effort to remove them (know any good taxidermists?) or
seek supernatural assistance to
reconstruct your bodySeek supernatural assistance, so I could see recovery powers as being supernatural way to recover.
Whether or not it fits the 'classic slasher' trope, I don't know.
You may want to think of stunts:
"JUMP SCARE"
Add +2 to stealth when ambushing teenagers/camp counselors
Unholy pursuit:
+2 to Investigate checks when you are the 'cat' in a cat and mouse contest.
There may already be similar stunts in the book.
