Can anyone help clear up the costs of magic items? I am looking at some magic items and the costs only say "+1 enhancement cost." For an example I will use the "Flaming" enhancement. Before an item can have a magical effect, it has to have a +1 enhancement in the first place. +1 enhancement is 2000g on its own. So would the "Flaming" enhancement be another +1 at the cost of 2000g for the total of 4000g? Or would they be considered a +2 enhancement combined and cost a total of 8000g? (This is of course seperate form the base item cost+masterwork price) I am trying to look at the information here, and I am having a hard time interpreting it. http://www.d20srd.org/srd/magicItems/magicWeapons.htm
When special abilities modify the enhancement bonus, you use the total enhancement bonus to determine cost. This applies to weapons, armor and shields.
Your example of a +1 Flaming weapon has a +2 enhancement bonus and thus costs 8000g + base item and masterworking.
Some qualities from outside of the SRD have direct cost modifiers like +300gp. These just add on to the price instead of changing the enhancement bonus.
