Creeping Decay

You gain this spell on a roll of 42 or 92 on the Forbidden Spells Table.

One creature you target within range receives 1d4 compounding necrotic damage.  Starting on any turn in which the creature took 12 or more necrotic damage that creature spreads the decay to each creature within 10 feet of it at the start of its turn.  Those creatures then begin to take 1d4 compounding necrotic damage and can spread it starting with the first turn they take 12 or more necrotic damage.  A remove curse or greater restoration can neutralize the effect on a creature.
