Moving onto 2nd edition Oriental Adventures there are a few new monsters in this book that were not in 1e. Converting them here.
I was going to skip these originally as I thought they were a bit silly, but, then I thought of Attack on Titan and realised that these can actually be pretty cool if done right. I know the reptilian gargantua is inspired by Godzilla but I consider these kaiju and in the league of the tarrasque.
Kyojin, or gargantua, are truly monstrous species, both in size and ferocity. Whether they are throwbacks to another age, aberrations of nat- ural processes, or results of crazed magical experiments is un- known.
Gargantua appear in many different forms, but most resemble gigantic humanoids, insects, and reptiles.
The reptilian gargantua is so immense that it dwarfs virtually all of the world’s creatures. Some reptilian gargantua move on all fours. Most, however, are bipedal, supported by two massive legs rivaling the width of the largest tree trunks. The creature’s body is thick and bulky. Rocky scales—usually dark green with black accents—cover it from head to toe. Its smooth belly is a lighter shade of green. Certain rare types have mottled scales in shades of brown, gray, and yellow.
Humanoid gargantua are the least intelligent type. They resemble gigantic humans, somewhat anthropoid facially, with stooped shoulders, long arms, and jutting jaws. Long, greasy hair dangles about their shoulders, though a few humanoid gargantua are completely bald. They stand 80 to 100 feet tall and are sometimes covered with black, brown, or golden fur. Their skin color ranges from pale pink to dull yellow to deep black. They have blunt noses, huge ears, and bright eyes, which are usually brown or red. Single-eyed humanoid gargantua also are rumored to exist.
Adult insectoid gargantua resemble immense moths. Their bodies are covered with fine fur, usually gray or black, and their wings bear colorful patterns in brilliant blue, red, yellow, and green. Their movements and other actions are accompanied by a pierc- ing screech that sounds like a warning siren.
Though extremely rare and generally cause for an entire army to be mobilised to deal with, their are rumours of an isolated island filled with nothing but kyojin and small kingdom of humans who battle these titans daily for control of the island and survival blissfully unaware of sprawling human civilisations outside their walled city.
A beast, humanoid, giant, or monstrosity can become a kyojin. When a creature becomes a kyojin, it retains all its statistics except as noted below.
Type. Change its type to monstrosity and its subtype to titan.
Size. Change to gargantuan and update HD and HPs appropriately.
Abilities. The creatures Intelligence is reduced to 5 if it is higher and its Strength and Constitution is increased by 6 to a maximum of 30.
Resistences. The kyojin is resistant to all attacks.
Immunities. The kyojin are immune to bludgeoning, piercing and slashing from nonmagical attacks that are not adamantine.
Languages. The kyojin looses any ability to speak though it still has a dim emphatic intelligence.
Challenge. Use the guidelines in the Dungeon Master’s Guide to recalculate the rating after you apply the template.
- Siege Monster. The kyojin deals double damage to objects and structures.
- Swallow. The kyojin 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 kyojin, and it takes ((CR/2) * d6) acid damage at the start of each of the kyojin’s turns.
- If the kyojin takes (1/10th its original hit points rounded up to the nearest tens) damage or more on a single turn from a creature inside it, the kyojin 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 kyojin. If the kyojin dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 30 feet of movement, exiting prone.
- Weak Spot. The kyojin has a weak spot which bypasses its damage resistance. The weak spot is specific to each creature type. For example, a humanoid kyojin has its weak spot on the back of its neck.
- Bite. If the base creature did not have a bite attack it gains one. Calculate to-hit and damage bonuses based on the kyojin’s Strength score and damage is 4d12 piercing and if the target is a creature, it is grappled (calculate escape DC normally). Until this grapple ends, the target is restrained, and the kyojin can’t bite another target.
- Slam. Replace any weapon attack with a slam attack that also grapples the target.
example using a hill giant.
