Wondrous Item, legendary (requires attunement by a being known as Death.)
This golden pendant looks like a balance with two skulls being weighed.
As a reaction, you can change one ability modifier with that of another one until your next turn starts.
If you are attuned to this amulet then you condense all of your other ability modifiers into one until the start of your next turn.
Notes: being known as Death., Buff, Jewelry
