Yijki World Destroyer

The Yijki World Destroyer is a flying multi-phase wither boss that requires using a variety of weapons to effectively defeat it. It is among the few airborne bosses on the server. It naturally spawns at the LMS but may be spawned manually using boss eggs.

Behavior

Yijki World Destroyer flies roughly 4 blocks high from the ground, is immune to fire damage at all times, and regenerates 1HP HP every second. It shuffles through various "phases" every 10 to 18 seconds. Despite being airborne, it frequently (every 15 seconds) spawns an army of aggressive wither skeleton minions.

Attacks

Shooting wither skulls (most common) is the main attack strategy. Skulls disobey gravity (always have linear motion) and explode on contact, causing a 3.5 radius explosion that inflicts enemies with Wither II (9 seconds).

There is a 33% chance every 15 seconds where the boss will trap nearby enemies in cages for 7.5 seconds. Cages are bedrock chambers with iron bars as walls. Caged enemies are immobile and take 1HP to 2HP HP damage every 0.5 seconds.

Minions have 40HP × 20 HP, up to 20 ( × 10) armor points, and are equipped with a diamond sword. Attacks inflict the enemy with Wither II (9 seconds). Each minion has a 33 to spawn with a Sharpness I-V diamond sword.

The boss will always spawn in axe, bow, or sword phase.
