Boss and broker rewards
Pearl from Scylla and the Sirens
The Oceanus boss reward provides a region-specific resource for Crossroads progression.
WHERE & HOW TO FARM
Pearl from Scylla and the Sirens
Scylla and the Sirens’ boss encounter at the end of Oceanus on the Underworld route.
Before you go
- Unlock the Underworld route and reach Oceanus.
- Progress to the boss chamber at the end of Oceanus.
- Prepare a build and resources suitable for completing the fight.
- Identify a current recipe or upgrade that uses Pearl.
Farming steps
- Choose the Underworld route and progress through Erebus into Oceanus.
- Clear the region’s rooms while checking any resource targets relevant to the run.
- Enter the boss encounter with Scylla and the Sirens at Oceanus’s end.
- Fight through the encounter and defeat the boss group.
- Collect the Pearl reward after victory.
- Return to the Crossroads and check the Cauldron or upgrade menu for the intended use.
- Spend the Pearl on the planned requirement when its other ingredients are ready.
- A Pearl is tied to beating the regional boss, so prioritize completing the encounter over searching rooms for it.
- Check the upgrade menu before the run so the boss reward feeds a current goal.
Repeat, collect and use
Repeat the Underworld route and defeat Scylla and the Sirens when another Pearl is needed for progression. This is a boss-clear reward, not a per-room gathering loop; collect it after victory and use it in the relevant Crossroads recipe or upgrade.
Common mistakes
- Searching Oceanus rooms for a Pearl deposit: the target is the boss reward at the region’s end.
- Leaving before collecting the post-fight reward: confirm the reward is collected after the victory.
- Running the route without a use in mind: check the Cauldron or upgrade goal first.
When to stop or switch
Stop making boss clears solely for Pearl once the planned requirement is met; choose the route for your next needed resource.
