Slip the Grasp

FEAT 9
Activity 1 action

Requirements You are Grabbed, Immobilized, or Restrained.

You have some feature that allows you to quickly evade effects that restrain you. Attempt a check to Escape. If you succeed, you can Stride, Step, or make a Strike with a melee unarmed attack targeting the creature you Escaped from. If you fail, you instead attempt to Escape a second time.

You increase your multiple attack penalty as appropriate for the actions you took, but only after completing both actions.
