How to farm
Before you go
- Complete The War Within and unlock Apollo.
- Bring a loadout that can stop Demolishers.
- Defeat key carriers and insert each color-matched key into its Conduit.
- Follow the Demolisher's sound and marker, then destroy it before it reaches the Conduit.
- Defend all four Conduits in each round for B rewards in the opening rounds and C rewards later; inspect each completed round for Axi S21.
Farming tips
- The relic appears in both B and C tables.
- Reward tables depend on round and Conduits defended; this mode is not a timed Survival rotation.
