Spite

When hit with an attack, you can spend a reaction to attempt to drain the attacker’s PP, if they are in range. Force the attacker to make a WIS save against your Move DC. On a fail, roll a d4. The PP of the move that attacked you is decreased by that number.

At Higher Levels: PP is drained by 1d6 at level 5, 1d8 at level 10, and 1d10 at level 17.
