Calculating cost of magic items.

[Kalandros]

Trying to figure out how exactly prices are added together.

+1 Fey Bane Cold Iron Battleaxe

MW Battleaxe 320
+1 costs 2000
Bane costs 2000 +1000 (2nd ability, +50%)
Cold Iron adds 2000

Did I forget anything or would the total be 7320 gold?

[Gauss]

Masterwork Cold Iron Battleaxe is 300 (MW) +20 (10*2 battleaxe)

The magic cost is:
2000gp to overcome the cold iron
8000gp for +2 effective weapon

Total price tag: 10320gp

Explanation:
Masterwork weapons are 300gp

Original price of the Battleaxe (10gp) is doubled

Magic Weapon properties have either a flat GP cost listed in the property or a +bonus that is totaled with all other properties the weapon has. That total is compared to the chart.

In this case you have a +1 enhancement and a +1 special property for a total of +2 effective price (8000gp).

[Honorable Goblin]

Battleaxe = 10 gp

Masterwork Weapon = +300 gp

+2 bonus (+1 enhancement, Bane special ability) = +8000 gp

Cold Iron = +100% Base weapon price (either 310 gp or just 10 gp, not sure here); +2000 gp for it being enchanted.

So grand total for purchase should be 10,320 - 10,620 gp.

Also, what Gauss said.

[Kalandros]

I see, so even if it says "Price +1 Bonus" I have to add up all the bonuses on it to determine its total cost.

How about adding enchantments to a +1 Battleaxe (or whatever weapon really)?

If its already +1 and I want to have it enchanted with Furious, for example - will it cost me 6000 to add Furious?

Original item is +1, which costs 2000 gold, newly enchanted item becomes +2 which is worth 8000 gold.

Honorable Goblin,

Weapons made of cold iron cost twice as much to make as their normal counterparts (not counting masterwork costs).

So, it is 320 for a Masterwork Cold Iron Battleaxe.

Kalandros,

Yes, you pay the difference to have it upgraded.

+1 Cold Iron Battleaxe = 4320gp
+2 Cold Iron Battleaxe = 10320gp
Difference = 10320-4320 = 6000gp.

You pay 6000gp to upgrade it to +2.
