Quaking Stomp (manipulate)

Frequency once per minute

Effect Jaiban stomps the ground with intense force. It creates a minor earthquake with the effects of the Earthquake spell, except that the range is only 100 feet and is contained to a 20-foot burst.

Trample

Huge or smaller, foot, DC 36 basic Reflex

The monster Strides up to double its Speed and can move through the spaces of creatures of the listed size, Trampling each creature whose space it enters. The monster can attempt to Trample the same creature only once in a single use of Trample. The monster deals the damage of the listed Strike, but trampled creatures can attempt a basic Reflex save at the listed DC (no damage on a critical success, half damage on a success, double damage on a critical failure).

Whip Tail (sonic)

Jaiban cracks its tail, creating a sonic boom in a 5-foot burst centered on a corner within reach of its tail Strike. Each creature in the burst's area must attempt a DC 36 Fortitude save.

Critical Success The creature is unaffected.

Success The creature is Stunned 1.

Failure The creature is Stunned 2.

Critical Failure The creature is Stunned 3.

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 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.
