Blood Funnel

A whirlwind of blood envelops an area you can see in range, forming a cylinder 30 feet tall with a 15-foot radius.

Creatures that enter the funnel for the first time on a turn, and those who end their turn there, must make a Constitution saving throw or be blinded. This form of blindness persists while the creature is within the funnel, and for 2d6 rounds after exiting the funnel. Additionally, creatures that enter the funnel for the first time on a turn, or those that end their turn there, take 4d4 acid damage.
