The Umbral Eye / 虚空の蝕王オクルス
by monocola
The Umbral Eye is a summoned boss for Minecraft 26.1.2 on Fabric, a single fight staged across three phases and set around one idea.
What it does
The boss is summoned by a ritual and fights across three phases, each marked by telegraphed attacks that give the player a chance to react. Phase shifts apply Wither, Hunger and Darkness, and the fight is tuned so that even a full set of enchanted netherite armor, a beacon and golden apples leaves only a narrow margin of victory. Players are expected to rely on potions, positioning and timing rather than raw gear.
The mod is client and server, so the server and every player need it. Its files target 26.1.2 only, with 1.0.0 as the latest Fabric build, published on 2026-06-09. The author notes a creative-only spawn egg, English as the automatic client language and a crafting recipe for an Umbral Catalyst that becomes available once a player obtains an Echo Shard, an Eye of Ender and Crying Obsidian. The license is All rights reserved, so the mod is not open source.
Key features
Umbral Lunge
A telegraphed dash that knocks back anything it reaches, giving the player a visible window to step aside.
Shard Nova
A radial shockwave that spreads outward from the boss, with a ring that the player must move out of.
Umbral Wisps and Eclipse Beam
Fast flying adds join from phase two, and in phase three the Eclipse Beam tracks locked positions that the player has to dodge sideways.
Void Meteors
Marked ground impacts land in phase three and force the player to keep moving rather than standing still.

What the author says
A floating, void-themed boss for Minecraft 26.1.2 (Fabric), built around one idea: a barely-winnable endgame fight. It's tuned so that even full-enchanted netherite + a beacon + golden apples is a knife's-edge victory. "Just swing and shoot" gets you killed — you'll need potions, positioning, and timing.
