Ammo Finder Bricks grant 27.5% [60%] {100%} of a Regular Ammo Brick's Pickup Amount, with decreased variability. Scavenger Mod's Bonus is applied to Ammo Finder Bricks. Pickup Amount is determined on Brick Spawn. Works on a Counter that only progresses with Weapon Kills. Once at 100%, the next Weapon Kill will spawn an Ammo Brick. Enemy Combatant Rank does not affect Counter %. Counter Percentage per Kill: Power: 1.1% to 1.33%. Average of 83.5 Kills. Special: 1.66% to 1.8%. Average of 57.25 Kills. Primary Weapons Kills = 4.25x | 3.25x Multiplier to Counter. Special Weapon Kills = 1.05x | 1.1x Multiplier to Counter. Exotic Primary Weapons = 5.05x | 4.75x Multiplier to Counter. Multiple ammo Finder mods do not increase the drop chance, just the amount of ammo per Brick
