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)

1. 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

2. Build the altar — a 3×3 with a Sculk Catalyst in the center, ringed by 8 Crying Obsidian.
3. 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）

1. 「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

2. 祭壇＝中央：スカルクカタリスト／周囲8マス：泣く黒曜石
3. 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。
