The next time you attack a creature with a melee weapon before the end of your turn, your weapon is imbued with bright lights. You gain a bonus to your weapon attack roll equal to your spellcasting ability modifier.

On a hit, the attack deals an extra 3d10 radiant damage to the target and the target is blinded until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the target extra damage increases by 1d10 for each slot level above 3rd.
