Big-Game Carver is a gear perk that increases how much meat you get from animals. It helps you stock up for La Cantina Meals and material trades.
Each animal you loot gives extra meat. Fewer hunts are needed to fill your supply for Meals and trades.
Wear one of the gear pieces that carry it: Paddock Bracelet, Primal Bracer. Each piece only takes one body slot, so plan around the other perks you want.
Worth it on dedicated hunting trips. Swap it out for a combat perk before an operation.
Stacks well with the Improved Hunter's Lodge upgrade, which also adds extra meat per carcass.
