Each boss wakes once an hour, twenty minutes after the one before: Old Carapace on the hour, Vorgrath at twenty past and Elderhorn at twenty to. The whole island hears three minutes before one wakes, in a notice and the raid warning across the screen, and again when it wakes and when it falls. If nobody is fighting it when its fifteen minutes are up, it goes back to sleep until its next hour.

Each fights as a raid boss does, in three phases. From the start it marks heroes to run apart. Below 60% life it brings in feeders that crawl to it and heal it unless they are stopped, and marks one hero for the group to gather on. Below 25% it enrages and channels behind a ward that has to be broken before the channel ends, while it goes on marking heroes to spread. Its heaviest blow on a Defender stacks a rend, so Defenders take turns, and it goes berserk after seven minutes. Its marks, warnings and life bar reach everyone within 160 metres.
- Phases
- Spread; feeders and a mark to gather on (60%); enrage, a ward to break and spread (25%)
- Scales
- Its life is set for ten fighters, heroes and companions alike: 30% of it for one, 61% for five, all of it for ten or more
- Berserk
- After 7 minutes
- Heard within
- 160 m
Everyone who fought it shares the kill: everyone on its threat list, and their party members within 90 metres when it falls. A companion's work counts for its hero. There is no tagging: two groups that never met both get it.
- Who
- Everyone on its threat list, and their party within 90 m
- Companions
- Count for their hero
Each character's first kill of each boss in a week earns its spoils, straight into your bags: one of the boss's two uniques at a 30% chance, 15% more for each time it has missed you, until one drops and the luck starts again. Otherwise the spoils are a rare item two levels above the boss and 80 gold plus 15 for each of your levels. Kill it again that week and you share the kill, but not the spoils. The week turns on Wednesday at 07:00 UTC, with the raids' lockouts.

A lone hero or a small party can call companions to the fight. Stand within 70 metres of a lair while its boss is awake and press Call companions to the fight under World Bosses in the Encounter Journal (X): up to four named companions come to fill your party to five, in the roles it is missing, at your level or 40, whichever is higher. They go once you are more than 220 metres from the lair, or when the boss falls.
- Where
- Within 70 m of the lair, while it is awake
- How many
- Up to 4, to fill a party of five
The map marks each lair with a horned diamond, its name and how long until it wakes (“Wakes in 12 min”), or a pulsing red ring and “Awake!” while its boss is up. The Encounter Journal (X) lists the three under World Bosses: where and when each wakes, its lore and abilities by role, the uniques it can give, whether you have had this week's spoils, and when they reset.
