The eidolon Strides twice and then makes a Strike. As long as it moved at least 20 feet, it gains a +2 circumstance bonus to the attack roll.
Primal Roar
(auditory)The eidolon attempts to Demoralize each enemy within 30 feet; these Demoralize attempts don't take any penalty for not sharing a language.
Rend
Claw
A Rend entry lists a Strike the monster has.
Requirements The monster hit the same enemy with two consecutive Strikes of the listed type in the same round.
Effect The monster automatically deals that Strike's damage again to the enemy.
Scent of Blood
Requirements A creature within the eidolon's scent range is taking bleed damage
Effect The eidolon flies into a frenzy, gaining 10 temporary HP for 1 minute and a +4 status bonus to damage rolls with its unarmed attacks, but becomes Off-Guard. It can't voluntarily end the frenzy or start another frenzy while in the frenzy. The frenzy lasts for 1 minute, after which the eidolon is Fatigued for 1 minute.
Grab
Requirements The monster's last action was a successful Strike that lists Grab in its damage entry, or the monster has a creature Grabbed or Restrained
Effect If used after a Strike, the monster attempts to [/act grapple] the creature using the body part it attacked with. This attempt neither applies nor counts toward the creature's multiple attack penalty.
The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
This creature is intended to be used as the eidolon accompanying a Sarkorian god caller, but it can be used or adapted into any aggressive beast eidolon for a summoner.
