History of Court of Blades Flawless

Court of Blades Flawless is a 10-point triumph: complete the Court of Blades activity without dying.

How to complete

1. Court of Blades is a private, 10-minute boss rush with a 45-second break between rooms. Use each break to restock ammo and buy Armaments with Runes (DualShockers recommends the Sigil, Armament, Echelon, Remunerate and Adamantine Runes).
2. Clear adds so your supers and heavy ammo aren't wasted, then focus the Challengers (bosses). Screen Rant advises choosing buffs that cover your own pain points.
3. Watch each room's Augmentations and hazards (for example "Gaze of the Deep") shown on the Hive statues.
4. Standard difficulty is easier and a good place to practice; whether Standard counts for this triumph is unconfirmed. The linked YouTube video shows a solo flawless Expert run of all 13 Challengers if you want to see a route.

Notes

The Heresy title guide I opened does not list this triumph, so its seal and any reward are unconfirmed.
