Crawling Hand

Tremorsense (Imprecise) 30 feet — 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.

Lifesense 30 feet — Lifesense allows a monster to sense the vital essence of living and undead creatures within the listed range. The sense can distinguish between the vitality energy animating living creatures and the void energy animating undead creatures, much as sight distinguishes colors.

Void Healing — A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Mark Quarry — A crawling hand can be assigned a quarry by anointing the hand with a drop of the intended quarry's blood. If the hand ever has no quarry, it automatically gains the next creature it damages as its quarry. The hand gains a +1 circumstance bonus to Perception checks when it Seeks its quarry, to Survival checks when it Tracks its quarry, and damage rolls when it Strikes its quarry.

Throat Grab — This ability functions as Grab, but the crawling hand grips the throat of a Medium or smaller creature. A creature Grabbed or Restrained this way has difficulty speaking and must spend an extra action to perform any action that requires speaking, including casting spells.

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.
