Key to the StomachEquipment 9

Weight negligible
Whether due to the inconvenience of having a physical body or the desperation of impending starvation, you were drawn to a person offering relief from hunger. You swallowed a key, which remains in your stomach, that continuously satiates you. You no longer need to eat or drink. Once per day, from any distance, the entity that holds your bargained contract can have the key sealing your bargained contract absorb all items in your stomach, which prevents you from benefiting from items that require you to eat or drink them, such as potions and elixirs, for 10 minutes. During this time, the entity gains the benefits of these items instead.

Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
ContractA contract is a type of item that magically establishes an agreement between multiple parties and typically grants magical benefits.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
