Primary Bulwark is a Primary Arcane that grants weapon damage based on your Warframe's Armor. The bonus is additive to other base damage buffs like Serration.
Roathe at La Cathédrale in the Sanctum Anatomica sells it for 5 Maphica, and the Steel Path Descendia can hand it out weekly. Infernum 6 and 13 give one copy, Infernum 20 gives three. It rewards tanky, high-armor Warframes.
Primary Bulwark was added with Update 41.0 (December 2025).
Primary Bulwark is tradable, see the current prices in the market box above.
