Dander (aura, olfactory)

Melee Claw +38 (agile, finesse, reach 20, unarmed), Damage 4d6+17 slashing

Pounce

The psstpsstmitl Strides and makes a Strike at the end of that movement. If the psstpsstmitl began this action Hidden, it remains hidden until after this ability's Strike.

Sneak Attack

The psstpsstmitl deals 2d6 extra precision damage to Off-Guard creatures

Topple

The psstpsstmitl swipes one giant paw across the battlefield in a 30-foot cone. All creatures in the cone must attempt a Reflex save.

Critical Success The target is unaffected.

Success The target is pushed 10 feet away from the psstpsstmitl and is knocked Prone

Failure The target is pushed 20 feet away from the psstpsstmitl and is knocked prone.

Critical Failure As failure, and the target is Stunned 2

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.
