Astral Disintegration

Channel the destructive power of the astral plane to disintegrate your target. If you target a creature, they must make an Intelligence saving throw, taking 3d6 Psychic damage on a failure and becoming frightened until the end of your next turn. If this spell would reduce the target creature’s hit points to 0, and the target is of a CR equal to half the spells slot level used on this spell or lower, the target is disintegrated. Example: if the spell is cast at 1st level and reduces a CR 0.5 creatures hit points to 0, the creature is disintegrated. If you target an object or a construct, you instead deal 3d6 Cold damage and if this damage would destroy the object, the object is disintegrated, leaving no trace behind.
