Ammo Case is a mod that allows the  Carrier sentinel to convert any unused ammo type into ammo for the currently equipped weapon and provides increased ammunition capacity. Converted ammo is denoted by a symbol. It is given to players upon claiming  Carrier ( Prime) from the Foundry or buying a  Carrier from the Market.

See Module:DropTables/data to edit on the wiki. Notes[] The extra 25% ammo maximum is added depending on your weapons' modded ammo maximum (any negative percentage will be offset only by up to 25% of the weapon's own final ammo maximum value). Mutation Efficiency is the same for all ranks and equivalent to a Rank 3 Ammo Mutation Mod. The amount of ammo received depends on the equipped weapon and follows the respective mutation mod for the equipped weapon. Other mutation mods stack with this effect, however the mutation delay will always be applied. Conversion effect does not work with Atmospheric Archguns. Trivia[] Ammo Case was added as a replacement mod for Carrier's  Vacuum precept, with all copies of Vacuum converted to Ammo Case. However, copies of Vacuum acquired after Hotfix: The Vacuum Within 2 (2016-10-06) will not be converted. Bugs[] Due to its mutation delay, sometimes it will consume more than enough ammo pickups in range. Sometimes multiple ammo pickups will be consumed even if you need just 1 bullet. For bows, every shot potentially consumes a lot of ammo pickups within 12m if you have a maxed  Vacuum equipped. Patch History[] Hotfix 22.20.4 (2018-05-22) Fixed Carrier’s Ammo Case precept continuing to function after it has died. Hotfix 19.6.3 (2017-01-17) Fixed Ammo Case Mod upgrades remaining after death. Hotfix: The Vacuum Within 2 (2016-10-06) Changes: Changed the Mod image for Ammo Case to better reflect its role. Fixes: Fixed Ammo Case still applying its buffs after Carrier has died. Fixed Ammo Case refilling ammo on respawn. Fixed Ammo Case refilling ammo on Host Migration. Hotfix: The Vacuum Within 1 (2016-10-05) Fixes: Fixed a crash that would occur when Ammo Case would trigger on a weapon with no ammo ( Exalted Blade, etc). Update: The Vacuum Within (2016-10-05) Carrier’s precept has been automatically changed to Ammo Case - now increases ammunition capacity and converts ammo pickups into ammo for the currently equipped weapon after a short delay.
