Consumes a number of stacks from the specified item in the character's inventory. If the cost cannot be paid, this reports a Gameplay Tag back to other abilities to handle the cost. This is used in Lyra for Ammo consumption and reload tracking. GA_Weapon_Fire_Shotgun and similar abilities use an Item Tag Stack additional cost set to Lyra.ShooterGame.Weapon.MagazineAmmo. Every time the weapon fires, the MagazineAmmo stack is decreased by the consumed amount. This prevents them from activating if the player runs out of ammo in the current weapon's magazine.
