Ammo bag
The ammo bag increases total ammunition capacity for all guns. Its listed tiers require wild boar, bharal, and clouded leopard skins, respectively.
How it works
This is a broad reserve-capacity upgrade across guns, rather than an upgrade to damage or accuracy. IGN recommends it as an early priority for a direct-combat approach. The excerpt also names a special fourth tier, but does not identify its hide requirement.
When it helps
Useful to prioritize when your approach depends on sustained gun use.
