Carving a Path of Light

Your weapon glows with astral light, and as it strikes your enemy, that glow spreads to encompass all enemies adjacent to you, temporarily coating them with a glowing target your allies can see. The next time you hit a creature with a weapon attack before this spell ends, the take a extra 3D10 radiant damage and until the end of your next turn, your allies have advantage against any enemy adjacent to you.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the extra damage increases by 1d10 for each slot level above 2nd.
