Terrorscream Shell

Very Rare Wondrous Item
Single use

Mindsplitter. You can use an action to activate and throw this item to a point within 45ft. of you. When it lands, it detonates. Horrible screams come forth from the shell. Each creature within 15ft. of the terrorscream shell has to make a Wisdom saving throw (DC 17). On a failed save they take 6d8 Psychic damage and are Deafened and Paralyzed until the end of their next turn. On a successful save they only take half damage and are not Deafened or Paralyzed.
