A twinned creature has grown a second head either due to a strange mutation, exposure to transformative magic, a truly unfortunate alchemical reaction, or simply by random chance. This additional head acts independently and could quite possibly have an entirely unique personality, depending on the intelligence of the creature.
Gnaw Free [Reaction] Trigger The twinned creature's other head attempts to Escape; Effect This head bites its grappler or restraints to help the other head break free. The twinned creature gains a +2 circumstance bonus to its Escape check.
