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.
