Planned for a members account. Building: in your house. Only single-step recipes are suggested, and the route only switches when another action is at least 10% better. Mahogany Homes contracts bundle many builds into one entry. Curved and long bones are rare drops, not a way to train.

Profit uses Grand Exchange prices from the OSRS Wiki, averaged over the last 24 hours. It assumes you buy materials and sell what you make straight away, paying the 2% GE tax. Furniture stays in your house, so there's nothing to sell back. Items with little trading are marked, since one trade can move their price.
