Hamstring 2014
Evocation cantrip
You create an arrow of eldritch energy and send it at a target you can see within range. Make a ranged spell attack against the target. On a hit, the target takes 1d4 force damage, and it can’t take reactions until the end of its next turn.
At higher levels
The spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
