This Reliquary was crafted by the devourer as a replacement stomach for specific minions, it functions much the same as a Bag of Devouring, with some exceptions.
Shurkaan, the Devourer, the extraplanar being attached to the bag can sense whatever is placed inside the bag. Animal or vegetable matter placed wholly in the bag is devoured and lost forever. When part of a living creature is placed in the bag, as happens when someone reaches inside it, there is a 95 percent chance that the creature is pulled inside the bag. A creature inside the bag can use its action to try to escape with a successful DC 18 Strength check. Another creature can use its action to reach into the bag to pull a creature out, doing so with a successful DC 20 Strength check (provided it isn't pulled inside the bag first). Any creature that starts its turn inside the bag is devoured, its body destroyed. The bearer of the bag is immune to this trait.
Inanimate objects can be stored in the reliquary, which can hold any amount of such material. However, once each week, the bag swallows any objects inside it and spits them out into another plane of existence. The GM determines the time and plane. The bearer of the bag receives a warning up to 1 minute in advance in the form of extreme queasiness and their stomach gurgling loudly. For the duration or until the bearer manually pukes up the contents (requiring an Action), or until Shurkaan spits the contents out, the bearer suffers the effects of the poisoned condition. If the bearer spits the contents out, they take 1d6 slashing damage for every object with a bladed edge, they can make a Constitution saving throw to receive half as much damage. The bearer can also spend the entire minute removing the objects to avoid the repercussions. Shurkaan can also be persuaded with a successful Charisma (Persuasion) check to not spit everything out, this check has advantage if something tasty is offered, and automatically succeeds if something new is offered.
Bearers of this item cannot benefit from eating nonmagical food, as it all gets eaten by Shurkaan instead.
As trade for progress on your bet, The Devourer grants additional toughness the first time any progress is made each day. The first time anything is fully consumed by the bag each day, you gain 2d10 temporary hitpoints, they last until the next standard mealtime.
