Erratic Circulation

You attempt to seize control of the blood flow of a creature you can see within range, forcing it to make a Constitution saving throw. On a failed save, the creature is knocked prone and becomes incapacitated until the end of your next turn, as you cause its blood to spasm and flow irregularly.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature for each slot level above 1st.
