The Abyss

This card has a charge time of five; Upon use,
select up to three of your own Treasure Cards,
and sacrifice them to this. Sacrificed Cards do
not drop any rewards, but each card grants a
random stat up.

(You may also stack Active Items inside The
Abyss as well - without the Active Item Slot.)

"Until it slowly withers away and is lost in the
abyss and void of nothingness."
