WHERE & HOW TO FARM
Undercity Tribute of Titans for Lair Boss materials
Kurast Undercity Spirit Brazier using a Tribute of Titans, followed by the timed district route and District Boss.
Before you go
- Undercity unlock quest completed and access to the Kurast Bazaar.
- A Tribute of Titans in inventory; verify its in-game reward description.
- A build able to finish the route and boss under the activity timer.
Farming steps
- Inspect the Tribute of Titans at the Spirit Brazier and verify its displayed reward focus.
- Read any offered Bargain and confirm its cost and condition are manageable.
- Commit the Tribute and enter the timed Undercity route.
- Defeat enemies and interact with available beacons to build Attunement on the way to the boss.
- Reach and defeat the District Boss before the run ends.
- Open the end chest, collect the boss-summoning materials and check their use in your current boss progression.
- Save the Tribute for a run where its reward is useful and any Bargain is achievable.
- Track the boss materials you actually need instead of accumulating supply without a target.
Repeat, collect and use
Repeat only while you have Tributes of Titans and need boss-summoning materials. Tributes are consumed, and the chest payout follows its displayed reward rules.
Common mistakes
- Assuming the Tribute grants a particular key directly: inspect the chest output and use the materials as described in game.
- Starting a Bargain you cannot satisfy: check its condition before spending the Tribute.
- Leaving before the District Boss chest: finish the route and boss to collect the reward.
When to stop or switch
Stop when your required boss-summoning supply is sufficient or your Tributes are gone; return to the relevant boss loop rather than accumulating materials you do not need.
