Artifacts and Bosses
by hboshears3
Artifacts and Bosses is a NeoForge mod for 1.21.1 that adds four bosses, five gems and a Buffs slot to the inventory.
What it does
Gems dropped by the new bosses are equipped in a Buffs slot, which opens from a light-gray button near the player icon in the inventory. Each gem grants a permanent buff, and the bosses are set up as high-risk, high-reward fights that get tougher as the player progresses. A final boss sits at the end of the chain, and it can only be reached by finding a location in the world rather than by crafting a spawn egg.
The mod lists four mobs, one block, two items and two tools, along with 12 achievements. One boss has low health and deals heavy damage with a burst of speed, and its Speed Gem makes the player fast. The Distorted Heart flies and launches heart projectiles, and its drop adds five more hearts. The Godly Summoner is placed in an Unholy Fortress to summon the final boss.
The mod runs on the client and on the server, so the server and every player need it. Files exist for NeoForge only, for 1.21.1, with 1.0.1 as the latest file published on 2026-03-05. The code is not open source, and the mod is released under All rights reserved.
