Turn to Fireflies

A thin golden ray springs from your pointing finger to a target that you can see within range. The target can be a creature, or an object.

A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 8d6 + 30 radiant damage. If this damage leaves the target with 0 hit points, it dissolves them into a swarm of fireflies.

If the target survives, all attacks against them are made with advantage until their next turn, or for the next 6 seconds, whichever is shorter.

An affected creature and everything it is wearing and carrying, except magic items, is turned into a swarm of fireflies equal in mass. The creature can be restored to life only by means of a true resurrection or a wish spell.

This spell automatically dissolves a Large or smaller nonmagical object or a creation of magical force. If the target is a Huge or larger object or creation of force, this spell dissolves a 10-foot- cube portion of it. A magic item is unaffected by this spell.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 3d6 for each slot level above 6th.
