Iaido

Iaido is the two-piece set bonus of the Bushido armor set. It restores 35 HP when you land a final blow shortly after drawing or reloading a weapon. The heal has a short cooldown, so hotswapping between weapons does not chain it.

Bushido armor drops from any Pinnacle Ops activity, usually as end-of-match rewards.

The four-piece bonus is Unfaltering Focus.
