As an action, each creature and object in a sphere twice as big as normal within 10 meters is outlined in blue, green, or violet light (your choice). An unwilling creature must make a Fortitude saving throw to avoid the effect. For the duration, objects and affected creatures shed dim light in a 2-meter radius.

Any attack made against an affected creature or object has advantage if the attacker can see it, and the affected creature or object can’t benefit from being invisible.
