4d8+10 bludgeoning damage, DC 41 basic Fortitude save

The monster deals the listed amount of damage to any number of creatures Grabbed or Restrained by it. Each of those creatures can attempt a basic Fortitude save with the listed DC.

Grasping Hands

The mutant's various hands stretch and reach out in an attempt to grab nearby creatures. The mutant attempts an Athletics check to Grapple all creatures within 10 feet. The mutant's multiple attack penalty doesn't increase until it has made all the Athletics checks that are part of its Grasping Hands. Creatures that are grabbed are pulled to a space adjacent to the mutant. This is forced movement.

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.
