Unbreakable Grip #Microfeats
Prereq: Str 13.
Benefit: When you have successfully grappled a creature, that creature takes a -5 penalty to any grapple checks it makes until it successfully makes a grapple check against your CMD.
You also do not have to make a Climb check to avoid falling if you take damage while using the Climb skill.
This feat counts as Improved Unarmed Strike for any feat prerequisite that also has Improved Grapple as a feat prerequisite.
