FAQQ: Does this work without MythicMobs?
No. SLBossSpawner uses MythicMobs to spawn and manage boss entities. MythicMobs is required.
Q: What happens if a boss is alive during server restart?
The boss state is saved to disk automatically. On restart, the boss is re-spawned at its last position with remaining time preserved.
Q: Can players who disconnect mid-fight still get rewards?
Yes! Damage/tank/support contributions are tracked in real-time. If a player reconnects before the boss dies, their stats are preserved. Pending rewards for offline players are saved and delivered on next login.
Q: Can I use MySQL for cross-server leaderboards?
Yes! Switch
database.type to "mysql" and configure your credentials. Connection pooling is built-in for performance.Q: Do I need PlaceholderAPI?
No, it's optional. If installed, you get PAPI placeholders for scoreboards, holograms, and TAB plugins.
