One of the most reliable ways to make money in House of Necrosis is by collecting consumable items and weapons during your runs, then selling them to the Trader. While the starting investment (such as the 30 Coins needed for a Rescue Crystal) may seem steep, a successful escape with multiple high-value items can yield profits that easily surpass your initial cost.
This guide compiles the known selling prices of consumables, equipment, and weapons. It will be updated as more items are discovered and verified.

Prioritize Herbs & Hexes: These sell for 25–29 Coins consistently and are easy to collect in most areas.
Avoid dying with loot: Escaping alive is more profitable than hoarding.
Stack duplicates: Trader accepts multiple copies — no diminishing return.
