Bosses - the full roster

Bosses live in their real OSRS lairs with OSRS-style combat. Type ::bosses in-game for the full teleport list, ::boss <name> for a fuzzy match, or use the home portal's Bosses tab.

The roster

Entry bosses

King Black Dragon - ::kbd. Multi-way lair. Drops dragon bones, rune gear, dragon dart tips; rares include KBD heads, Draconic visage and the Prince Black Dragon pet. 10 Boss points per kill.

Kraken, Cerberus, Giant Mole, Kalphite Queen, Sarachnis, Thermonuclear Smoke Devil, Demonic Gorillas, Skotizo, and the Dagannoth Kings (::dagannoth_rex, ::dagannoth_prime, ::dagannoth_supreme) - each boss has its own ::<name> command (e.g. ::kraken, ::cerberus, ::thermonuclear_smoke_devil).

God Wars Dungeon (multi-way, team-friendly)

City bosses - the War's own bosses (currently the Corporeal Beast at Lumbridge) work differently: pooled damage-split loot, sponsor tithes and troop shares. See Corporeal Beast.

Collection log

Notable boss drops are tracked automatically - you'll see a "New Collection Log slot" message on a first-time drop.

::clog - opens the native OSRS collection log interface
::cl - plain text readout of every category and what you've ticked off

Rules worth knowing

Lairs marked multi-way above allow team PvE (and in the wilderness, team PvP).
Wilderness boss trips risk everything under normal death rules - killers get your loot in a loot key.
Boss kills pay Boss points as tradeable ticket items - spend them at the reward shops in the Lumbridge market.
