Yamamoto Origin: Ryūjin Jakka adds the Captain-Commander of the Gotei 13 as a playable Origin for Fabric 1.20.1.
The Origin
- Immune to fire and lava
- 14 hearts and +30% movement speed
- 30% damage reduction
- 25% more melee damage
- A fire aura while the sword is equipped
Ryūjin Jakka, the legendary sword
- It can’t be crafted, and only one legitimate copy can exist per world.
- The first Yamamoto to awaken becomes its permanent owner, and the owner is saved with the world, so it survives restarts.
- Illegitimate copies are deleted, whether from
/give, creative mode or duplication. - Dropped swords can’t be destroyed by lava, fire or explosions, never despawn, and are rescued from the void.
- If the owner dies, the sword always comes back on respawn, even with a full inventory.
/yamamoto recallreturns it at any time. - The Unworthy: anyone else who holds it takes 50 hearts of fire damage per second and can’t use it. If they die, the chat shows “[Name] wasn’t worthy of Ryūjin Jakka.”
Shikai (key R, V to cycle, B to use)
- Flame Slash, a flaming wave
- Ennetsu Jigoku, pillars of fire
- Jōkaku Enjō, a ring of flame that lasts 10 seconds
- Ryūjin Jakka Release, a huge explosion of fire
While Shikai or Bankai is active, every hit adds 5 HP of fire damage and sets the target on fire.
Bankai: Zanka no Tachi (key G, lasts 2 minutes)
- It plays Yamamoto’s Bankai sound and chars the blade.
- East, Kyokujitsujin: all the flame goes into the blade tip, the world darkens, and hits do extra armor-ignoring and fire damage.
- West, Zanjitsu Gokui: a spinning column of fire burns everything near you.
- South, Kakajuman no Kushi Daisōjin: a horde of glowing skeleton warriors fights for you.
- North: a huge forward slash.
- The land scorches and evaporates around you during Bankai, and everything is restored when it ends.
Tenchi Kaijin 天地灰尽 (key H) is the ultimate attack: a blackout, a white flash, then a massive, extremely high-damage wave.
Enchantments
- Flame Ascension I–IV: direct damage of 10 / 12 / 14 / 15 and bonus fire damage of 2 / 4 / 6 / 8.
- Blazing Tempo I–IV: attack speed of +10 / +20 / +35 / +50%.
- Both come from librarians and village chests.
- Only sword-type enchantments work on the sword. Sharpness, Protection and other off-type enchantments are blocked.
Requirements: Fabric Loader, Fabric API and Origins.
