Editing Expeditions (section)

== Guardian bosses ==

Each biome is ruled by a single '''Guardian'''. Defeating a biome's Guardian for the first time '''unlocks the next biome''' in the chain, opening up its patrol and, once fully cleared, its cave. Guardians are much harder than patrols and reward a unique trophy item. They remain repeatable — the boss you farm for the best drop rates.

Percentages in the Outputs column show the chance of that drop; items without a percentage are guaranteed on every win. Intervals are base times before speed bonuses. Every run — patrol or Guardian — can also drop an Expedition Set piece and the biome's Dig Site Map; see '''[[#Rewards|Rewards]]''', below, for those rates.
