Bombardier's Spray (acid, primal)

The cataclysm beetle sprays a 60-foot cone of acid from its abdomen that deals 12d10 acid damage (DC 40 basic Reflex). It can't use Bombardier's Spray or Burning Pool for 1d4 rounds.

Burning Pool (acid, primal)

The cataclysm beetle spills acid directly from its abdomen, creating a wave of acid that deals 10d12 acid damage to all creatures in a 30-foot emanation (DC 40 basic Fortitude). Creatures that fail this save are pushed back 10 feet from the cataclysm beetle (30 feet on a critical failure). It can't use Bombardier's Spray or Burning Pool for 1d4 rounds.

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.
