Charges case

Does it earn its slot?

Bought at 10c and sold back at 1–2c, this loses money on a round trip — as almost all gear does. It is meant to be used, not traded. The question is only whether its effect is worth a slot on the run you carry it.

What a ammo slot is for

Ammunition is priced per shot and stored per slot, and those two facts pull against each other. Buying loose rather than bundled is almost always the better deal unless you are topping up between runs.

The opportunity cost is the honest way to judge any of it. Your pack is the binding constraint, and the same slot could come home holding a Metal Idol worth 80–120 at the Basic tier and 560–840 at Legendary, or two bottles of wine at up to 720. At 1–2c, this item is not competing on resale — it earns its place through what it doesduring the run, or it doesn't earn it at all.

For the 10c this costs, the shop will also sell you a Machete (5c, 22 damage) with change left over. Whether that trade is right depends entirely on the contract — which is the argument for reading it before you shop.
