Frequently Asked Questions

Demon Alchemy help?

How do I do the Tamayo mission?

  • The quest system is still work in progress, the Tamayo mission hasn't been implemented yet

What do I do after Final Selection?

  • Take your ore to a swordsmith and get your sword (see How do I get to swordsmith village?)

How do I get sun breathing?

  • Wait for the mod to update, the new sun breathing is WIP
  • Or go into the config and disable enhanced black sword, that will let you use Orca's black sword from the base mod

How do I get to swordsmith village?

  • Go find a kakushi, hold a scarlet ore in your hand, then the kakushi will ask if you want to go to the swordsmith village. Click YES, and then equip the blindfold on your head slot
  • To find a Kakushi, open the meditatio nmenu (by sitting on a cushion), and click hte Navigation tab, and then scroll down to "Swordsmith Village" on that list of locations in the bottom left, and click on Swordsmith Village to select it. Your crow will now point you towards the nearest Kakushi entity

Help I have the item stacking glitch

  • There is a glitch where if you hold an item then suddenly new items of that same type will no longer be able to stack on that item
  • "_if i tried picking up 4 blocks of wood one would just go into another corner while the other 3 were in a stack_"
  • FIX: update to version 1.6.443 or higher

Where did the the custom swords go?

  • The new swords (like ice and frost) are now in KnY Extra Additions
  • curseforge.com/minecraft/mc-mods/kny-extra-additions
  • https://modrinth.com/mod/kny-extra-additions
  • https://github.com/YeeticusFinch/KnY-Extra-Additions/

My world creation is stuck at 100%

  • UPDATE: Region files for Mt Fujikasane and Swordsmith Village are now in this mod:
  • https://modrinth.com/mod/kny-worlds
  • This means that Mt Fujikasane isn't importing properly
  • Try upgrading to the latest version of Kimetsunoyaiba Tweaks
  • Otherwise, you can fix it manually:
  • Go to your .minecraft folder --> kimetsunoyaibamultiplayer --> mt_fujikasane_cache
  • If this folder is empty, then you've got a problem
  • https://github.com/YeeticusFinch/KimetsunoyaibaTweaks/tree/main/region
  • ^^ Download all the region files from this GitHub link
  • Place all those .mca files into minecraft/kimetsunoyaibamultiplayer/mt_fujikasane_cache/
  • Reload the mod and try again

Where can I get help with this mod?

  • I don't usually check comments on the mod page
  • If you need support, please join on discord: https://discord.gg/W8K962vQFT
  • Or send an email to carlfromca@gmail.com

The game crashes on mod loading

  • Make sure you have forge 47.4.0
  • Make sure you have the forge versions for 1.20.1 for all the following dependency mods
  • Kimetsunoyaiba
  • Mob Player Animator
  • Player Animator
  • GeckoLib
  • KnY Worlds
  • Make sure you don't have Optifine, it's completely incompatible

My spawns are messed up, there are no Hashira or Kizuki demons or named characters spawning?

  • Go into the config for Kimetsunoyaiba Tweaks (aka Kimetsunoyaiba Multiplayer)
  • Disable enhanced spawning
  • Enhanced Spawning will prevent named characters, hashira, and kizuki demons from spawning - outside of raids and quests and special biomes/structures

How do I configure this mod?

  • I recommend using a config mod, like Configured or Forge Config Menus
  • Alternatively, you can go into your minecraft folder --> config --> Kimetsunoyaiba Multiplayer
  • You can edit the .toml files directly

Missing textures

  • Yes sorry I haven't finished making all the assets yet

Features

Quest System

This mod adds a new quest system for players in 4 different tracks: demon slayers, demons, kakushi, and swordsmiths.

See the Quests Wiki for up-to-date information on the quest system. The quests are still in early beta.

Meditation Menu

To access the meditation menu, right click a cushion to sit on it, and then click the meditate button.

The meditation menu gives you access to stats (your current rank, how many kills...), navigation (selecting your waypoint, you can set it to navigate to a quest or a location, good for finding structures), and skills (essential for demons).

Custom Blood Demon Art Builder

The Custom Blood Demon Art Builder is accessed in the Skills tab in the Meditation Menu (access it by sitting on a cushion).

You can select your eyes, and you can select a color and particles for your custom blood demon art. As you level up, you will unlock more slots for forms for your blood demon art.

Each form is a list of moves. First form can only have one move, second form can have up to two moves, third form can have up to three moves...

There are some basic moves that every demon player starts with (like punch and front flip). To unlock more moves, use Demon Alchemy to make Catalysts.

CustomNPC Support

This mod offers basic support for Custom NPCs to use nichirin swords and breathing forms.
