Revive Three Classic Unused Mobs: Giant, Killer Bunny, and Illusioner

1. Giant

• Spawn: Fix contradictory light condition (light < 8 && light > 11 → standard hostile spawn: light < 7, any Overworld biome)

• AI: Restore 18wXXa snapshot AI (2× zombie speed, 50 damage on Normal)

• • Hate trigger:

    • When health drops below 25%, the Giant begins to smoke (visual warning)

    • If any player attacks it while it's below 25%, or if a player reduces it to below 25%, it becomes hostile toward that player

    • Speed and damage then activate (2× speed, 50 damage)

•  

2. Killer Bunny

• Cannot spawn naturally. It must be player-created through an extremely rare ritual:

  • Biome: Plains (surface only)

  • Time: Daytime (clear weather)

  • Target: A rabbit with exactly Poison, Slowness, and Weakness (no other effects)

  • Environment: 5+ different hostile mobs within 16 blocks (undead excluded — they burn in daylight)

  • Player must be within 32 blocks

  • Transformation chance: Adult 5%, Baby 1% (while conditions hold)

• Stats: Same as original Killer Bunny (3 HP, 8 armor, fast, attacks players/wolves)

• Self-immolation (Red Hulk tribute): After 60 seconds chasing same target → catches fire, dies after 120 seconds no target

• Reward: 1000 XP on death — huge payoff for the insane effort to create it

3. Illusioner

• Already fully coded (Blindness spell, clones + invisibility, wallhack vision, raid participation via command)

• Still maintained: 1.21.2 added "avoids Creaking" behavior

• Just enable it:

  • Spawn in Woodland Mansions (replace some Evokers)

  • Spawn rarely in Pillager Outposts

  • Join Raids from wave 4+

•
