Divineberry

Ten berries appear in your hand and are infused with magic for the duration. A creature can take a Bonus Action to eat one berry. Eating a berry at the same time as someone else, from the same source, induces a shared hallucinogenic state. Each creature that eats a berry must make a DC 15 Concentration (Wisdom) Saving Throw to remain focused on a person, place, object, or image. During this hallucinogenic state, you are effectively blinded to the outside world for the duration of the spell.

Uneaten berries disappear when the spell ends.
