Special Abilities

Drone (Su) The sound of a derakni in flight is a mesmerizing, unsettling drone that causes confusion in all non-demons who hear the sound. A derakni must fly at least 10 feet to activate this ability (which it can do as a free action as part of its move action). Any non-demon creature that begins its turn within 30 feet of a derakni that moved in this manner on its previous turn must succeed at a DC 18 Will save or become confused for 1d4 rounds. A creature that makes this save is immune to the drone of that derakni for 24 hours. Demons are immune to this sonic, mind-affecting effect. The save DC is Charisma-based.

Poison (Ex) Bite, blood, or sting—injury; save Fort DC 21; frequency 1/round for 6 rounds; effect 1d4 Con; cure 2 consecutive saves.

Vescavor Aura (Su) A mythic locust demon is surrounded by a small cloud of vescavors which float around it and envelop his personal space. The demon is completely unaffected by the swarm, but creatures who start their turn adjacent to the demon take 2d6 points of swarm damage and are confused for 1 round (DC 18 Will negates confusion and reduces damage by half ). The demon may spend one use of his mythic power to increase the damage to 3d6, which also ignores DR and increases the DC of the Will save by +2. As a move action, a mythic locust demon can detach its vescavor aura, transforming it into a vescavor swarm that obeys its mental commands. Its vescavor aura is suppressed as long as the vescavor swarm is active as a separate creature, and if the swarm is destroyed the locust demon’s vescavor aura is suppressed for 24 hours, though if the swarm is destroyed the demon can renew its vescavor aura as a full-round action by expending one use of its mythic power. The locust demon can reform the vescavor aura around itself as a move action when it is adjacen to the vescavor swarm. If the swarm has taken damage, it begins healing 1 point of damage per round and cannot be detached again until it reaches full hit points. The swarm cannot be damaged separately when attached to the locust demon as an aura. The save DC is Charisma-based.
