About this Mod

About mod

This mod is a comprehensive upgrade to vanilla Minecraft. It adds content exactly where the base game feels empty — new blocks, items, mobs, mechanics, unused features from Minecraft's own code, and even elements from official spin-offs (Minecraft Dungeons, Legends, and beyond).

A large set of new decorative and functional blocks. Useful items, including repurposed "unused" ideas originally found in Minecraft's game files. Content inspired by Minecraft spin-offs, plus original creations.

Several new regular mobs with unique behaviors.

Mobs can spawn enchanted. The higher the difficulty, the higher the chance — on Hard mode, enchanted mobs appear very frequently.

2 mini-bosses and 2 full bosses with unique attack patterns, phases, and rewarding loot.

This mod adds crafting recipes for several items that were previously unobtainable in vanilla.
New structures added to the world. Some new locations worth exploring.

Many small gameplay tweaks that make the game feel fresh without breaking the vanilla spirit.

(Still in development, everything can change) (some textures from Goety - The Dark Arts)
