The Elder Scrolls: Tamriel real

This iron bottle with a brass stopper can trap extraplanar creatures. As an action, speak its command word to target a creature within 60 ft. If it's not native to your plane, it must make a DC 17 Wisdom save or be trapped. A creature previously trapped has advantage. The flask holds one creature, which doesn’t age, eat, or breathe. You can release the creature as an action—it's friendly for 1 hour, obeying your commands unless suicidal. Afterward, it reverts to its nature.
