Absorb Shock

Whenever the stormdrinker would take electricity damage or is targeted with an electricity effect, it gains 10 temporary HP, is Quickened, and increases the reach of its vine Strikes by 5 feet until the end of its next turn. It can use its extra action to Stride, Strike, or Swim.

Effect: Absorb Shock


Speed 20 feet, swim 20 feet
Melee Vine +18 (reach 10), Damage 2d10+8 bludgeoning plus Grab
Lightning Blast
Requirements The stormdrinker is Quickened due to Absorb Shock

Effect The stormdrinker dismisses its Absorb Shock benefits to expel lightning in a 60-foot line, dealing 8d6 electricity damage (DC 25 basic Reflex save).
Ring Bell (auditory)
Requirements The stormdrinker is carrying a bell

Effect The stormdrinker rings its bell, signaling Tumbo to bite him once. (Multiple bites don't stack their effects on the stormdrinker.) The stormdrinker can't use this ability when it doesn't have its bell, such as if it is Disarmed.
Vine Lash

The stormdrinker makes a vine Strike against each creature within reach. Its multiple attack penalty increases only after all the attacks.

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.
