Batenkaitos' Gluttony

Pick a target within range below 25 hit points. That target must make a Charisma saving throw, gaining disadvantage on that throw if you know the target's name. On a failure, nothing happens. On a success, one (or both) of the following effects occur(s):

• Memory Eater. The target loses all of their personal memories, retaining basic functions and language. You heal HP equal to triple the number of years of memories the target had.

• Name Eater. Everyone loses all memories of the target, with their memories rewriting themselves to exclude the target. You heal HP equal to 5 times the number of friends the target had. This can only be used if you know the target's name.

If you choose to use both of the effects, the target falls into a permanent coma.
