Aetherwinds Tiered Bosses
Adds a tiered boss altar system to Aetherwinds SMP. Three altars — Tier 1, 2, and 3 — summon progressively stronger bosses (Wither, Warden, and a heavily empowered Evoker) for endgame players and teams to fight.
Features:
- Three altar blocks, each triggering a boss fight on right-click
- Tier 2 and 3 require a key item from the previous tier to unlock
- Bosses scale to survive real endgame damage output, with health tracked and displayed via a dedicated boss bar
- Only one boss active per altar at a time — no duplicate spawns while a fight is in progress
- Server-side utility mod built specifically for the Aetherwinds modpack
