CHP: Core — Minecraft Mods | NxLabs

From Modrinth

A simple core mod for Cave Horror Project.

Features made so far:

Icons for quest rewards _(for version 3.2.1)_
Announcement about Cave Horror Project: Origins _(for version 3.2.3 and 1.5.1)_
Welcome message _(for version 3.3)_
Made fortune work on Ancient Debris _(for version 3.3)_
Changed recipe for Netherite Ingot _(for version 3.3)_
World-specific config for From the Fog mod _(for version 3.5)_
New items obtainable either from Cave Dweller or The Man From The Fog - Torn Hide, Dweller Claw and Fog Fragment _(for version 3.6)_
New craftable items - Dweller Boots and Fog Crystal _(for version 3.6)_
Advancement for defeating a Cave Dweller _(for version 3.6)_

I don't really suggest using this as a standalone mod as it's only meant to add some custom features into Cave Horror Project.
