Brilliant Spear

A spear of divine light flies in a streaking blur towards your target. Make a ranged spell attack against the target. On a hit, the target takes 6d8 radiant damage, and has disadvantage on all attack rolls until the beginning of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
