illutioner-calamity

Illusioner: Calamity Descends

A Minecraft boss mod that transforms the vanilla Illusioner into a three-phase encounter with powerful attacks, dramatic effects, and a final curse that follows you beyond victory.

Compatibility

• Minecraft Java Edition 26.2
• Fabric Loader 0.19.3
• Fabric API 0.155.2+26.2
• Java 25
• Mod version 0.2.0

Install the mod on both the server and every connecting client. Compatibility with later Minecraft versions has not been verified.

Summoning

Drink an Ominous Bottle while affected by Hero of the Village to summon the boss. You need suitable nearby terrain, and another encounter must not already be active nearby. Summoning is unavailable in Peaceful difficulty.

Its arrival brings a thunderstorm to the Overworld, cinematic lightning, expanding particle rings, and ominous dialogue in chat.

The Boss

Illusioner: Calamity Descends uses the vanilla Illusioner model and has 1,500 health, divided into three phases of 500 health each. Phase transitions feature flashes, particles, and dialogue.

Attacks

The elite Zombie has 50 health, fully enchanted Netherite armor, and an enchanted Netherite sword. Its equipment does not drop.

Successful reinforcement summons produce five cinematic lightning strikes at the summoned creatures. These visual bolts do not damage creatures, start fires, transform mobs, or alter copper and lightning rods.

Damage values use Minecraft health points: 2 health points = 1 heart.

The Final Curse

Defeating the boss triggers an unavoidable final sequence for participating players.

The Illusioner immobilizes its victims, rises into the air, and fades amid spiraling particles and its final words. Affected players receive:

• Permanent Blindness
• Permanent Nausea
• Five pulses of void damage, dealing 20 damage per second for five seconds

The final damage sequence must be endured. Cleansing the permanent effects does not cancel the damage pulses. Death ends any remaining pulses for that life, but the permanent curse persists through death and reconnecting.

Removing the Curse

1. Eat an Enchanted Golden Apple.
2. Finish drinking Milk while at least one effect granted by that apple is still active.

Milk alone cannot remove the curse. Effects granted by other sources do not qualify or extend the cleansing window.

Advancement

Defeat the boss to earn Loyalty Endures — 忠诚永存.

Installation

1. Install Minecraft Java Edition 26.2 with Fabric Loader 0.19.3, using Java 25.
2. Place illusioner-calamity-0.2.0.jar and fabric-api-0.155.2+26.2.jar in your instance's mods folder.
3. Remove any older version of this mod from that folder.
4. For multiplayer, install the mod and Fabric API on both the server and all clients.
5. Launch the game and prepare your summoning items.

English and Simplified Chinese translations are included.

Administration

Operators with the required permission can use:

/calamity cleanse <player>

This removes the player's curse, pending final damage, and related movement restrictions.

Validation Status

Version 0.2.0 passed 9 unit tests, 45 mod GameTests, and a Chinese-language client cinematic test. Actual two-client multiplayer sessions and real server restart/reconnect scenarios still require manual verification.
