As an action, you can create this bomb. As an action, a creature can throw this bomb at a point within 5 meters, where it explodes on impact. Each creature and object in a sphere twice as big as normal centered on that point is outlined in blue, green, or violet light (your choice). An unwilling creature must make a Reflex saving throw to avoid the effect. For the duration, objects and affected creatures shed dim light in a 2-meter radius.
Any attack roll 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.
