How it works

Each room rolls the minute of birth within each boss's window: one roll per window, different from room to room, so you can't camp at a fixed time. When it spawns, the server announces in all rooms' chat: “(Room N) Boss appeared on the map! Go in party”.

The kill credit and the drop go to whoever deals the MOST DAMAGE in the final stretch of the fight, with the whole party's damage added up — not the last hit. The killer shows up in the server-wide announcement.

The drop starts reserved: only whoever carried the fight (and their party) can pick it up for a few seconds (on bosses, the reservation lasts longer than on regular monsters). After that, it's first come, first served.

The boss no longer leaves: it stays alive until someone defeats it, even after a server restart. After it dies, it spawns again once its interval has passed, counted from the time of death.

Bosses have high health and defense: go in a party.
