⚔️ EndBoss

End Boss for Paper 1.21: A 3-phase Wither Skeleton featuring adaptive AI that locks the End portal while alive.

Features

• 3 Configurable Phases (scale, speed, damage, cooldowns, abilities, regeneration) with a cinematic transition between each phase.
• Utility-Score AI: The boss selects its target (threat level, distance, line of sight, low health) and its attacks based on the situation, avoiding repetitive behavior.
• Player Adaptation: Detects bow usage, pillaring, and elytra flight, adapting its strategy accordingly.
• Telegraphed Abilities: Predictive leap, dash, flying swords, behind-the-back teleportation, Mace Smash, shockwave (dodgeable by jumping), summoned Vexes, and meteors.
• Defense Mechanics: Frontal shield breakable with an axe, projectile dodging, and counter-attacks.
• Terrain Interaction: Bridging, pillaring, wall-breaking, and anti-pillar tactics. All damage is restored automatically without item drops or permanent block loss.
• Regeneration: Slight passive regeneration in phases 2 and 3, fast regeneration if left out of combat.
• End Portal Lock: Locks the portal while the boss is alive (saved state, persists across restarts and chunk unloads).
• Individual BossBar, top fighters leaderboard on defeat, and customizable loot tables.
