Primary Bulwark is a Primary Arcane that increases weapon damage based on your Warframe’s Armor, making heavily armored Warframes even deadlier.
It provides a direct damage boost, scaling with Armor, so builds that stack defensive stats also benefit offensively.
Obtaining Primary Bulwark requires farming Maphica in The Descendia, but the extra damage makes it a worthwhile investment for high-armor setups.
How To Get Primary Bulwark?
Primary Bulwark can be purchased from Roathe at La Cathédrale in the Sanctum Anatomica, which unlocks after completing The Old Peace quest.
Each copy costs 5 Maphica, the currency used for all Arcanes sold by Roathe, and it may also appear as a reward in Steel Path The Descendia on a weekly rotational basis.
Maphica is earned by participating in The Descendia activity, so obtaining multiple copies or fully ranking up Primary Bulwark requires several runs and careful farming.
Primary Bulwark Effects
Primary Bulwark increases your weapon damage based on your Warframe’s Armor, allowing your offensive output to scale with your defensive investment.
At rank 0, each unit of Armor past 1,000 grants +1% damage, scaling steadily with rank until reaching a maximum of +500% at rank 5.
This Arcane works best on Warframes with high Armor values, letting weapons deal significantly more damage while the Warframe remains durable.
By tying weapon performance to Armor, Primary Bulwark provides a natural synergy for tanky builds, rewarding players who focus on survivability while maintaining high damage potential.
Primary Bulwark Farming Tips
The fastest way to gather Primary Bulwark is by collecting Maphica efficiently in The Descendia. Focus on completing Infernum floors while looting every crate and reward chest along the way.
Always extract safely once you reach a point where continuing may risk dying, as failing the mission forfeits any collected Maphica.
Repeating these runs steadily builds up enough Maphica to purchase Primary Bulwark without relying on random drops, ensuring consistent progress toward fully ranking this Arcane.
Verdict
Primary Bulwark is a powerful Arcane for Warframes with high Armor, converting their durability into increased weapon damage.
By stacking Armor, players can significantly boost their primary weapon’s output, making this Arcane especially effective in high-level missions with tough enemies.
Focusing on farming Maphica efficiently ensures you can acquire and rank up Primary Bulwark quickly, giving your Warframe both survivability and enhanced offensive potential.
