Speed Surgeon is a gear perk that greatly speeds up how fast your manual heal recharges. It lets you heal more often in a long fight, so you lean on your own healing instead of finding medkits.
Your manual heal comes back much faster after each use. You can patch up between waves of enemies without waiting long.
Wear the Revolutionary Gloves in the hands slot. Gear perks are fixed to the piece of clothing that carries them, so you get this one by wearing that piece, not by unlocking it in a menu.
Strong for loud, aggressive play and on harder difficulty, where healing often decides a fight.
