History of Unfaltering Focus

Unfaltering Focus is the four-piece set bonus of the Bushido armor set, which drops from Pinnacle Ops. Bow, shotgun or sword kills grant 10% damage resistance for eight seconds, and dealing sustained damage with those weapon types extends the effect. In PvP the resistance is reduced to 2.5%. It stacks multiplicatively with other damage resistance sources.

The two-piece counterpart is Iaido, which heals 35 HP on a final blow with a freshly drawn or reloaded weapon, with a short cooldown that stops it being triggered by hotswapping.
