Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.
30 feet. A creature that enters the area must attempt a DC 34 Fortitude save. On a failure, the creature is Sickened 2, and on a critical failure, the creature is also Slowed 1 for as long as it is sickened. While within range of Thessekka's stench, the creature takes a -2 circumstance penalty to saves to recover from the sickened condition. A creature that succeeds at its save is temporarily immune to all xulgaths' stenches for 1 minute.

Effect Thessekka commands nearby earth to attack a foe. Thessekka makes a claw Strike against a creature that is within 60 feet of her and 10 feet of an earthen surface, such as dirt, mud, stone, or sand. The Strike originates from the surface's square and has a reach of 10 feet. On a critical hit, the target is also knocked Prone.
Earthen Torrent(earth)
Frequency once per minute
Requirements Thessekka is standing on or next to at least 10 cubic feet of dirt, stone, or other earthen material
Effect Thessekka creates a violent wave of roiling earth. Creatures in a 15-foot cone take 10d10 bludgeoning damage (DC 34 basic Reflex save; on a critical failure, creatures are also knocked Prone).
Expanded Splash
Thessekka's bombs with the splash trait deal 4 additional splash damage and deal splash damage to all creatures within 10 feet.
Quick Alchemy
Cost 1 batch of infused reagents
Effect Thessekka creates a single alchemical item from her formula book (see Alchemical Formulas). This item has the infused trait, but it remains potent only until the end of her next turn.
Thessekka turns her own body into solid stone like a statue and immediately becomes Petrified. Any creature grabbed or restrained by her becomes Immobilized; to get free, the creature must damage the statue enough to break it or succeed at a DC 36 Acrobatics check to Escape. The only action Thessekka can take while petrified is to use Stone Throes again to end the effect.
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.
