Augur of Ebrietas

"Remnant of the eldritch Truth encountered at Byrgenwerth. Use phantasms, the invertebrates known to be the augurs of the Great Ones, 

to partially summon abandoned Ebrietas. The initial encounter marked the start of an inquiry into the cosmos
from within the old labyrinth, and led to the establishment of the Choir."

When this spell is cast, a number of large tentacles and slugs extend from the caster's hand. 

Make a ranged spell attack against the target. On a hit, the target takes 1d10 force damage.

The damage of this spell increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
