Features:

- Animated Attack Moves: Bosses use custom animations, telegraphed wind-ups, and on-screen alerts before casting strikes.
- Classic Summoning Rituals: Build shrines with gold blocks and fire to call down legendary enemies into your world.
- Unique Boss Weapons: Defeat encounters to earn special gear like the Blade of Herobrine with custom ranged slashes.
- Anti-Cheesing Rules: Bosses disable creative flight and elytra glides to keep combat grounded and fair.
- Entity 303 hovers in the air, fires glitching lasers, and spawns copies of itself.
- Herobrine dashes around the battlefield, dodges sword strikes, and calls down obsidian meteors.
- Special status effects like Grounded, Bound, and Erased challenge players during fights.
- Victories grant nether stars, rare gems, and unique challenge advancements.
Herobrine Combat:
- Cyborg phase starts the duel with the Void Blade and fast teleport strikes.

How to Use:
- Place nine Gold Blocks in a three-by-three square on the ground.
- Set a Netherrack block directly in the center on top of the gold square.
