I’ve been working on hacking various south and east Asian mythological creatures and monsters for use in my 5th Edition Dragonblade! game, and I’ll continue posting them up once they’re finished – or finished enough to put up on Obsidian Portal, anyway.
Nuppepo (medium fiend, lawful evil)
AC 10 (natural armor)
HP (6d8 +6) 36
Str +1, Dex -2, Con +1, Int -5, Wis +0, Cha -4
Resistances: cold, necrotic
Immunities: poison damage; charmed, frightened, poisoned, sickened
Darkvision 120’, passive perception DC 10
Languages: Common (Yamata), Abyssal
Devil’s sight: the nuppepo can see even through magical darkness
Fist +4 1d4 +1 bludgeoning
Nuppepo are vaguely humanoid mounds of rotting flesh, most often encountered in abandoned tombs and cemeteries.
Phaya Naga, or River Dragon (large dragon, any alignment)
HP 142 (15d10 +60)
Str +5, Dex +0, Con +4, Int +2, Wis +1, Cha +3
Saves: Dex +3, Con +7, Int +4, Cha +6
Immunities: thunder and force
Senses: blindsight 30’, darkvision 120’, passive perception DC 17
Languages: Common (Lao), Primordial (water or wood)
Multiattack: two claws, one bite
Bite: +8 2d10 +5 piercing
Claws: +8 2d6 +5 slashing
Some river dragons are spellcasters, and if so, they use their Charisma as their spellcasting ability, know three spells up to level 3, and have 3 spell slots. Spell attack +6, spell save DC 14.
Tsukumogami (Small or medium object or humanoid, unaligned)
AC 12 (natural armor)
HP 58 (9d8 +18)
Str +3, Dex +1, Con +2, Int -2, Wis +1, Cha -1
Immunities: acid, polymorph
Darkvision 60’, Passive perception DC 11
Languages: Common (Yamata)
Shapechanger: able to polymorph into any small or medium object or humanoid creature. When the Tsukumogami polymorphs into a humanoid the form includes clothing appropriate to its former (or current) owners.
False appearance: a DC 15 Wisdom (Perception) check is required to see that anything is out of the ordinary when a tsukumogami is encountered.
Grappler: the tsukumogami has advantage on all grappling-related rolls
Pseudopod or fist: +5 1d8 +3 bludgeoning, and the tsukumogami can grapple whether in humanoid or object form
Bite: +5 1d8 +3 piercing and 1d8 acid damage
Tsukumogami are an idea that exists in both Japanese and Korean folklore. The idea is that an object, once it is 100 years old or more, might wake up and became animated and sentient. It makes sense that objects left in dungeons, for example, would wake up a bit more often than others, since they would lay around forgotten in treacherous caverns for years on end. Just the kinds of places PCs end up.
