## Items add in the costs of their item separately from the magical properties.

If we look at the rules for [creating magic items](https://www.aonprd.com/Rules.aspx?Name=Magic%20Item%20Creation&Category=Magic%20Items), we see:

> Magic supplies for items are always half of the base price in gp. For many items, the market price equals the base price.  *Armor, shields, weapons, and items* **with value independent of their magically enhanced properties** add their item cost to the market price. *The item cost does not influence the **base price** (**which determines the cost of magic supplies**)*, but it does increase the final market price.

So when making +1 flaming longbow it would cost 4375 gp (8000 gp [base magic price] x 0.5 [crafting] + 75 gp [longbow] + 300 gp [masterwork]), and any price reductions for making magic items would only apply to the magic portion of its cost. E.G. [Spark of Creation](https://aonprd.com/TraitDisplay.aspx?ItemName=Spark%20of%20Creation) would further reduce it's cost by 200 gp = 8000 gp x 0.5 x 0.05.
