🧿 The Dark Doppelganger Boss

The Dark Doppelganger is a multi-phase boss fight designed for experienced players.

Boss Features

• Multi-phase combat with increasing difficulty
• Spellcasting melee and ranged attacks
• Teleports back from the void if knocked off the world
• Summons hostile minions during combat
• Dynamic boss music and boss health bar
• Scales stats and abilities based on configuration
• Designed for multiplayer encounters (supports multiple players fighting at once)

---

🔮 Boss Phases

• Phase 1: Standard spellcasting and melee attacks
• Phase 2: Increased aggression and new spell combinations
• Final Phase: Frequent minion summoning, life-drain abilities, and high pressure combat

The boss cannot be cheesed easily and is intended to feel like an end-game encounter.

👁️ Minions

The Dark Doppelganger can summon hostile minions during the fight.

Minion Behavior

• Attack players aggressively
• Do NOT attack the boss or other boss minions
• Automatically choose nearby players as targets
• Despawn when the boss is defeated
• Not player-owned and cannot be controlled

Minions are designed to pressure players, not act as companions.

• Summon Minion - Lets you summon your own minion

⚠️ Important

Summon Minion spell is NOT learnable by players and does not appear in the Scroll Forge.

These spells are used exclusively by the Dark Doppelganger and its summons, but defeating the boss gives you a chance at a spell drop!
