Entry requirements
Reach main character level 150, defeat each required Pinnacle, and spend one Grand Expedition Pass.
An unstable crossing between storm-port underways and unreceived garden courts.
Grand Expedition · Level 150+
Gutterbloom Underways
Masked patrols and forgotten caretakers keep the roads beneath overgrown gardens. Prepare for a trial of endurance; extraction opens only when the passage becomes unstable.
Equipment sources
Equipment is drawn from these source worlds with the listed relative weights.
- The Sable Writ Isles · weight 1
- Asterhome: The Unreceived World · weight 1
Each enemy has a separate 0.1% Unique-item roll. Bosses also have a 1% Legendary-item roll from the source world's eligible Pinnacle equipment.
Regional lore books →Run rules
- Entry consumes one Grand Expedition Pass. Its duration counts active expedition time, not offline time.
- There is no early return portal. When the pass expires, the party must reach an open extraction portal. Bring enough food, drink, and potions for the full run.
- Hardcore recruits can die permanently. In Softcore, a defeated recruit is unavailable until the expedition closes; a visit to Town does not clear that defeat. Grand Expeditions do not use the Tower and Dungeon rescue rules.
- Each new run rolls one to eight hidden expedition modifiers. Their identities and values are revealed after entering, not while preparing the portal.
- Enemy levels are chosen from the expedition's minimum through the main character's portal level limit. Each run uses the chosen range.
- Equipment draws from the two listed source worlds. Eligible equipment rolls independent bonus tiers for its base, implicit, signature, and affixes. Any positive tier marks the item Exalted; Exalted is not a separate rarity.
Passes
Boss reward rolls have a 1% chance to award a pass. The pass weights below apply after that roll succeeds.
