SPECIAL TRAITS

• False Appearance. While the pneumavore remains motionless without its underside exposed, it is indistinguishable from an island.
• Gargantuan Resistance. The pneumavore has advantage on saving throws against disease, poison, spells, and other magical effects.
  • Sense Inaequa. The pneumavore senses inaequa within 5 miles of it at will. This trait otherwise works like the detect magic spell but isn’t itself magical.
  • Siege Monster. The pneumavore deals double damage to objects and structures.
  • Water Breathing. The pneumavore can breathe only underwater.

ACTIONS

• Multiattack. The pneumavore makes three giant tentacle attacks. When encountered with Rogar, in order to avoid damaging him or his crew the corrupted pneumavore can only attack with one tentacle each round
• Giant Tentacle. Melee Weapon Attack: +12 to hit, reach 30 ft., one target. Hit: 25 (4d8+7) bludgeoning damage. If the target is Huge or smaller, it is grappled (escape DC 20) and restrained until the grapple ends. The pneumavore has 4 tentacles, each of which can grapple one target.
• Tentacle Slam. The pneumavore slams creatures grappled by it into each other. Each creature must succeed on a DC 15 Strength saving throw or take 25 (4d8+7) bludgeoning damage and be stunned until the end of the pneumavore’s next turn. On a successful save, the target takes half the bludgeoning damage and isn’t stunned.

ABOUT

The full body plate armor this figure wears would be advanced even for a Master Inquisitor and clearly is not of this world, the blades in their hands bleeding void into the air.
