How Much Does It Cost To Increase The Bonus To An Existing Magic Weapon?


Rules Questions


So, currently the one game I get to be a player in I play a cleric of Horus who uses a +1 axiomatic khopesh. How much would it cost me to increase the bonus to +2 or add another +1 ability? I'm not sure on the math. I don't want to wait to "find a better weapon" as this one was consecrated by Horus and it's part of her character background.


Price of the weapon you want to end up with minus the price of the weapon you have now equals the price you pay to upgrade to the weapon you want.

+1 axiomatic = +3 price equivalent = 18,000 gp (plus weapon cost, irrelevant here since it will be the same on both sides of the equation)

So whether you want a +2 axiomatic khopesh or, for instance, a +1 axiomatic flaming khopesh, the result is the equivalent of a +4 weapon.

A +4 weapon costs 32,000 gp (the price for weapons is bonus^2 x 2,000).

+4 cost (32K) - +3 cost (18K) = upgrade cost (14K)

So you'll need 14,000 gold to upgrade your weapon.

Yup, you just pay the difference.


Groovy. Thanks, guys!


Fixed price weapon abilities, material costs, masterwork cost and cost of the basic weapon are outside the above calculation and can be seen as being added on afterward.

Or 1/2 that amount (7k) if you have Craft Arms and Armor and spend 14 days upgrading it yourself. :)
