Ammo Reservation Potion

Ammo Reservation Potion is a buff potion which buffs the player with Ammo Reservation. The buff reduces the chance of consuming ammo by 20%. This lasts for 7 minutes, but can be cancelled at any time by right-clicking the icon. It seems to be a Call of Duty joke as ammo is used a lot in those games, and Call of Duty can be shortened to CoD.
