Poachers' Dens only begin to appear in Chapter 3. Here, any monsters that have been Poached will be turned into items that can be bought. Poached items are typically far less expensive then their counterparts in the Outfitters. Rare items can also be bought this way. All items sold to the Poachers' Den will remain there as part of its inventory. They can be bought again for the same price as they were sold.
