Erdan's Radiant Spear

"Think of it like Guiding Bolt, but with more piercing and screaming," - Erdan, a notable chaotic good cleric

A blinding bright arrow streaks toward a target within range and bursts in a spray of light. Make a ranged spell attack against the target. On a hit, the target takes 1d6 piercing damage and 4d4 radiant damage immediately. On a miss, the arrow blinds the target  if it striked within 10 ft. until next turn and leaves a notable scorch mark wherever it landed.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d4 for each slot level above 3rd.
