| Improved Grab (Ex): To use this ability, a wyvern must hit with its talons. It can then make a grapple attack or check as a free action without provoking an attack of opportunity. If it wins a grapple check, it establishes a hold and stings. If it establishes a hold with a grapple attack instead, it can sting. Poison (Ex): Injury; Fortitude DC 17; Frequency 1/rnd for 6 rnds; Effect 1d4 Con damage. Cure 2 consecutive saves. The save DC is Constitution-based. |
