Endless: Tier 9 (Hard) — Duviri

How to get here

This is the Steel Path Circuit (the Undercroft at full Steel Path scaling: +100 enemy levels, 250% health/shield/armor). To access it you need the base Steel Path unlock — all pre-New War star-chart nodes cleared, then talk to Teshin — PLUS The Duviri Paradox quest and the three base Duviri nodes cleared in normal mode. Past Tier 10 you reach Tier 11+, and every additional 1,400 Circuit progress re-rolls the "Repeated Rewards" pool — the Steel Path arcanes shown below.

• Tier 9 (Hard) awards 25× Steel Essence.
• Steel Path Circuit runs a separate 9-week Incarnon Genesis rotation (5 weapons/week).
