Divine PassWord

You know secret password to a harmless dimension that may be used to send each creature of your choice, within range, to a harmless plane. That creature makes a charisma saving throw. Regardless of its HP, a Celestial, Elemental, Fey, or a Fiend target that fails its save is forced back to its plane of origin (if it isn’t there already) and can’t return to the current plane for 24 hours by any means short of a Wish spell.

The creature's HP determines how long they will remain in the plane. Any creature with 40 HP or lower will gain the Frightened debuff, unless that creature is sent back to its plane of origin.
