Bouncy Body

The target’s flesh becomes flexible and rubbery. It gains resistance to bludgeoning damage, and advantage on Dexterity (Acrobatics) checks against being grappled and to escape from a grapple. Anytime the target would take falling damage, it treats falls as 20 feet shorter (minimum 0) for the purpose of determining damage. In addition, if the target falls against a hard surface, it can attempt a Dexterity (Acrobatics) check (DC = 1 per 5 feet fallen) to attempt to bounce upward; success means the creature bounces upward half the distance fallen.
