The Umbral Eye — 虚空の蝕王オクルス
A floating, void-themed boss for Minecraft 26.1.2 (Fabric), built around one idea: a barely-winnable endgame fight.
⚔️ The Fight
The Umbral Eye is not another humanoid mob — it's a levitating eldritch eye that circles you in the air and rains telegraphed attacks across three escalating phases. Every attack has a clear wind-up (particles + sound), so the fight is about reading and dodging, not tanking.
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.
Attack patterns
- Void Volley – spread of homing void bolts (magic damage, ignores armor)
- Umbral Lunge – telegraphed dash with knockback
- Shard Nova – radial shockwave; back out of the ring
- Umbral Wisps – fast flying adds (phase 2+)
- Eclipse Beam – tracks, then locks; dodge sideways during the lock (phase 3)
- Void Meteors – marked ground impacts that force you to move (phase 3)
- Phase shifts apply Wither / Hunger / Darkness — pressure that bypasses armor and punishes passive play
🌑 Summoning (Survival)
- Craft the Umbral Catalyst — the recipe unlocks the moment you obtain an Echo Shard, Eye of Ender, or Crying Obsidian:
E C E E = Eye of Ender
C S C C = Crying Obsidian
E C E S = Echo Shard
- Build the altar — a 3×3 with a Sculk Catalyst in the center, ringed by 8 Crying Obsidian.
- Right-click the center with the Catalyst, at night under open sky. The void tears open.
(A creative-only spawn egg is also included.)
🏆 Rewards
A curated drop table — Netherite Ingots, Diamonds, Enchanted Golden Apples, Echo Shards (to re-summon), and a guaranteed Nether Star — plus a big XP payout and a full advancement line from Whispers of the Void to the Eclipse's End challenge.
⚙️ Multiplayer & Config
- Player scaling — boss HP scales with nearby players (fair in groups; solo top-gear stays "barely winnable").
config/umbraleye.json— HP multiplier, scaling, XP, boss music, ritual toggle.- Server-friendly: no block griefing.
📋 Requirements
- Minecraft 26.1.2 · Fabric Loader 0.19.2+ · Fabric API · Java 25
- Required on both client and server (custom model + server-side AI)
🌐 Languages: English & 日本語 (auto by client language).

宙に浮く眼球状の高難度ボス「虚空の蝕王オクルス」を追加します(Minecraft 26.1.2 / Fabric)。コンセプトは一つ——「ギリギリ勝てる」終盤ボス。
人型ではない浮遊ボスが、空中から予兆付きの攻撃を3段階で繰り出します。各攻撃にパーティクルとSEの溜めがあるので、本質は読んで回避すること。フルエンチャ・ネザライト+ビーコン+金リンゴでも薄氷の勝利になるよう調整しており、素直に殴る/撃つだけでは倒せません。
攻撃パターン:虚空の弾幕(防具貫通)/影の突進/虚空衝撃波/ウィスプ召喚(P2〜)/蝕の光線(P3・横回避)/虚空隕石(P3)。フェーズ移行でウィザー・空腹・暗闇を付与。
召喚(サバイバル)
- 「蝕みの瞳」をクラフト(エコーシャード/エンダーアイ/泣く黒曜石のいずれか入手でレシピ解放)
E C E E=エンダーアイ
C S C C=泣く黒曜石
E C E S=エコーシャード
- 祭壇=中央:スカルクカタリスト/周囲8マス:泣く黒曜石
- 夜・開けた空の下で中央を触媒で右クリック
報酬:ネザライト・ダイヤ・エンチャ金リンゴ・エコーシャード・ネザースター+大量XP、進捗4種。
マルチ・設定:人数でHPスケール、config/umbraleye.json で調整、ブロック破壊なし。
