by Alexjcqin

Core Keeper Fabric brings the world, mobs, bosses, dimensions and magic of the Core Keeper game into Minecraft as custom content.

What it does

The mod adds a new dimension filled with danger and treasure, along with custom mobs and bosses drawn from Core Keeper. Glurch, the Abominous Mass, is an enormous orange slime boss that uses jumping attacks and enters a rage mode before dropping epic loot. Orange, Purple, Blue and Lava variants of the slime behave differently, and Hive Acid types carry special drops.

An RPG stat system ties the new content together. Crit, dodge, armor, mining speed and minion power all feed into it, and ten skills cover areas such as mining, running, melee, magic, summoning, explosives, vitality, crafting and gardening, each leveled to a cap of 100. Eighty talents spread across skill trees, which players open with K. A respec tree is available after three experience levels.

Equipment adds two ring slots, one necklace slot and one backpack slot to the inventory, with the backpack opened using B. Accessories drop on death. A magic barrier shield regenerates in layers over the hearts. Core Keeper Fabric is published for Fabric only, and the mod runs on client and server, so the server and every player need it. Its only release targets 1.21.
