Astrid's Starry Wisp

You launch a beam of burning light in any direction originating from you. Everything other than you within a 15-foot long, 5-foot wide Line must succeed a Charisma saving throw or a take 2d4 Radiant damage.

Success or failure, the area where the Line was emits Dim Light in a 10-foot radius until the end of your next turn. Any creature or object that ends its turn within this light can’t benefit from the Invisible condition until the end of its next turn.

Cantrip Upgrade. The damage increases by 2d4 when you reach levels 5 (4d4), 11 (6d4), and 17 (8d4).
