Endurance

Since the Knee Pad of Speed increases your stamina drain by 80%, but the Oxygen Tank of Hold Breath reduces it by 40%, you can run for twice as long at top speed. With the stamina recovery boost, you can take much shorter breaks. Snipers and SMGs seem to work effectively, snipers because you can relocate faster after you shoot, SMGs cause you can close gaps faster. it also can effectively create a ambush situation with a melee weapon in a building.
