Armor Focused Decoding

Armor Focused Decoding is a tab in Commander Zavala's vendor inventory in the Tower that sells the Ferropotent suit for your active class, such as the Ferropotent Bond for Warlocks. Select the tab, then pick the suit for your class.

Each piece costs one Vanguard Engram and 15,000 Glimmer. Higher-tier versions unlock at higher Power, with Tier 5 available around Power 550. Vanguard Engrams are earned through Vanguard Ops, with one granted per Vanguard Rank.
