In Creating Magic Items - Potions: the rules state "The character must pay the full cost for brewing each potion" - which is the same cost as just buying a potion.
However, the feat Brew Potion says "To create a potion you must use up raw materials costing one half [the] base price". Which is more in line with the other Item Creation feats, but it links you to the information listed above.
Which is correct?
Must pay the full crafting cost, which is half of the market price. That's my reading and supported by other crafting feats.
Lol.. i see this now.. I should probably sleep.. thanks
