WHERE & HOW TO FARM
Where to farm
On Duty → Wrath of the Worldkillers → Besieged Titans Tower Solo or Walk-In Solo.
Enter Besieged Titans Tower alone and follow the mission objectives through the Diasporan attack and corrupted Titans technology. The rescue and Tower objectives must be completed for the instance to count; confirm rewards in On Duty.
Worldkillers chapter access and solo instance eligibility.
A character prepared for the available solo difficulty.
The Besieged Titans Tower entry visible in On Duty.
Open On Duty and choose Besieged Titans Tower’s solo entry.
Review the selected version’s reward panel and launch it.
Advance through Diasporan forces, following the instance objective markers.
Address corrupted Titans technology when the objective directs you to it.
Locate and rescue the trapped Titan trainees indicated by the tracker.
Continue through the remaining Tower objectives until completion registers.
Claim the instance reward and check inventory for the resulting chapter items.
Farming tips
Follow objective updates rather than clearing every optional-looking enemy in the area.
Make sure trainee rescue progress is complete before leaving the instance.
Repeat, collect and use
Repeat the solo entry while it remains eligible for its listed reward. Respect any reset limit displayed by the game. Use Titans Tokens for a chosen chapter vendor item and retain S.T.A.R. Labs materials for their designated progression use.
Common mistakes
Mistaking a solo entry for a group queue: confirm the mode before launch.
Fighting past a required interaction: check the tracker for corrupted technology and rescue actions.
Exiting before completion registers: wait for the finished state, then claim the reward.
When to stop or switch
Stop after the desired reward is claimed or the solo entry reaches its displayed eligibility limit; switch to the duo if you prefer a partner run.
