Summoner (Unchained) › Greater Aspect

Trip (Ex)

Source: Pathfinder Unchained, p. 37

The eidolon becomes adept at knocking foes to the ground with its bite, granting it a trip attack. Whenever the eidolon makes a successful bite attack, it can attempt a free combat maneuver check. If the eidolon succeeds at this check, the target is knocked prone. If the eidolon fails, it is not tripped in return. This ability works only on creatures of a size category equal to or smaller than the eidolon. Requirements: Daemon, demon, devil, elemental, or protean subtype; bite evolution.
