Tweaked from 5eYou already know this as 5e Moonbeam — It's your Moonbeam — a lingering light zone that hits anything entering or starting its turn inside it — but beefed up to 4d10 necrotic with a level of exhaustion and a Faerie Fire-style glow that strips invisibility. ✨
Fill a 30-foot sphere with radiation for 10 minutes; creatures inside save or take 4d10 necrotic and gain one exhaustion level.

Dim, greenish light spreads within a 30-foot-radius sphere centered on a point you choose within range. The light spreads around corners, and it lasts until the power ends.
When a creature moves into the power's area for the first time on a turn or starts its turn there, that creature must succeed on a Constitution saving throw or take 4d10 necrotic damage, and it suffers one level of exhaustion and emits a dim, greenish light in a 5-foot radius. This light makes it impossible for the creature to benefit from being invisible. The light and any levels of exhaustion caused by this power go away when the power ends.
