Monstrous Monday: Gargantua Demons

We had tickets to see the new Godzilla: King of Monsters movie this weekend so we made a day of it. Went out and played Pokémon Go as a family and we all caught a Tyranitar in a raid.  We all renamed them after Kaiju, except for my youngest who in his typical fashion named his "Greg".

We saw the movie. It was great fun and everything you want a Godzilla movie to be; giant monsters beating each other up while leveling a city.  Then we went out to have sushi and another round of Pokémon.

Of course, this got me thinking about my Gargantua Demons of my game world.  I thought I should update them for today.

Special Traits

---

• Legendary Resistance (3/Day): If the gargantua fails a saving throw, it can choose to succeed instead.
• Magic Resistance: The gargantua has advantage on saving throws against spells and other magical effects.
• Siege Monster: The gargantua deals double damage to objects and structures.

• Actions

  ---

  • Multiattack: The gargantua can use its Frightful Presence. It then makes four attacks: one with its bite, two with its claws, and one with its tail. It can use its Swallow instead of its bite.
  • Bite: Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 36 (4d12 + 10) piercing damage. If the target is a creature, it is grappled (escape DC 20). Until this grapple ends, the target is restrained, and the gargantua can’t bite another target.
  • Claw: Melee Weapon Attack: +19 to hit, reach 15 ft., one target. Hit: 28 (4d8 + 10) slashing damage.
  • Tail: Melee Weapon Attack: +19 to hit, reach 20 ft., one target. Hit: 24 (4d6 + 10) bludgeoning damage. If the target is a creature, it must succeed on a DC 20 Strength saving throw or be knocked prone.
  • Frightful Presence: Each creature of the gargantua’s choice within 120 feet of it and aware of it must succeed on a DC 18 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if the gargantua is within line of sight, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to the gargantua’s Frightful Presence for the next 24 hours.
  • Swallow: The gargantua makes one bite attack against a Large or smaller creature it is grappling. If the attack hits, the target takes the bite’s damage, the target is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the gargantua, and it takes 60 (20d6) acid damage at the start of each of the gargantua’s turns. If the gargantua takes 80 damage or more on a single turn from a creature inside it, the gargantua must succeed on a DC 20 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the gargantua. If the gargantua dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 30 feet of movement, exiting prone.
  • Breath Weapon (Recharge 5–6):  The gargantua exhales fire in a 90-foot cone. Each creature in that area must make a DC 25 Dexterity saving throw, taking 82 (15d10) fire and necrotic damage on a failed save, or half as much damage on a successful one.

  • Legendary Actions

    ---

    • The gargantuan can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The gargantua regains spent legendary actions at the start of its turn.
    • Attack: The gargantua makes one claw attack or tail attack. 
    • Move: The gargantua moves up to half its speed.
    • Chomp (Costs 2 Actions): The gargantua makes one bite attack or uses its Swallow.

These horrors are destruction incarnate. These demons stand over 50 feet tall and are horrible to behold.  Each one is unique, but all have characteristics in common.  They are typically humanoid in shape but could be covered in scales, leathery skin, fur, chitin, or any combination of these. Their intellect is below that of animals and like all calabim demons, they exist only to destroy.

Powerful Baalor or even Arch Fiends can control them, but it is difficult to do.  Mostly they are sent somewhere where everything must be destroyed or eaten.  Gargantua will even fight and kill other demons.

All gargantua have massive claw and bite attacks in addition to tail, horn or other weapon attacks.  Occasional on a bite attack a victim can be swallowed whole.  Every gargantuan also has a breath weapon attack. Typically fire, but lighting and wind are also common.

Human wizards and warlock have been known to try to summon these creatures but the destruction they cause usually outweigh any perceived benefits they may offer.  The spells to do so are carefully guarded.
