Damaging Light

Note: This spell is a greater version of Revealing Light.

An improved version of the Light cantrip, you point to a visible location of your choice within range, and select creature and/or objects you can see within that range no larger than 10 feet in any dimension within a 20' cube. Each target failing a saving throw takes immediate 3d8 radiant damage. The affected targets sheds bright light in a 20-foot radius and dim light for an additional 20 feet. The light can be colored as you like. Completely covering a creature or object with something opaque blocks the light. The spell ends if you cast it again or dismiss it as an action.

Targeted creatures, or objects held or worn by hostile creatures, may use a Dexterity saving throw to avoid the spell entirely. Objects not worn by a creature have no saving throw, and the spell effects are automatic. If you target an object held or worn by a hostile creature, that creature may roll a Dexterity saving throw to avoid the spell on the object. Each target may roll a separate saving throw to avoid damage and effects of this spell.

Any attack roll against an affected creature or object has advantage if the attacker can see it, and the target can't benefit from being invisible. Targeting the source of light from this spell targets the creature or object. The light moves with affected creatures and/or objects until the spell ends.

The spell scales with spell level: cast at 3rd level, 3 objects and/or creatures are targeted. For each spell level beyond 3rd, an additional object or creature is targeted, and damage increases by 2d8.
