Chiyoko

Chiyoko predicts the outcome of certain loot tables before they happen by simulating the RNG exactly as minecraft does.

• 1.21.11 support is currently being worked on, this might take a while.

Commands

/validateseed

verifies that the world seed configured in chiyoko matches the server's seed hash

/predict <enchant1> <level1> [<enchant2> <level2>] [<enchant3> <level3>]

searches ahead using the cracked entity seed to find how many item drops are required to obtain the desired enchantments.

supports up to three enchantment/level pairs

---

Limitations

• cannot predict unstable RNG, such as the number of bones required to tame a wolf
• cannot automatically obtain the world seed in multiplayer
• uses the 1.20+ loot table system and therefore cannot support versions before 1.20

---

Known Issues

• enchant predictor "best guess" doesnt require the guess to include the enchant clue
