Eike's Piercing Projectile

A light blue sparkling thin projectile appears in the air and goes completely straight to the target. Make a ranged spell attack against the target. On a hit, the target takes 4d8 force damage. This projectile is spectral and pierces through any material except silver, adamantine, mithral, and lead.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
