I'm a little confused about purchasing magic weapons, and I was wondering if someone could confirm or correct my math.

+1 Corrosive Masterwork Composite Longbow - Str Adjusted + 2

Composite Longbow 100gp
Masterwork 300gp
Strength adjusted +2 200gp
+1 magic property 2000gp
+1 Corrosive 8000gp (???)
=
10,600gp
Giving +2 Att, +2 / +1d6 Dmg

Almost. [+1 corrosive] is equivalent to [+2], and +2 costs 8k, so you end up at 8,600.


By my calculations, it's only 8,600 gp.

Remember, the +1 price bonus is included in a +2 price modifier. So when reading the chart for price, if it says +2 = 8,000 gp, it already has included the price of a +1 enhancement. When you upgrade a +1 weapon to a +2 weapon, you only pay 6,000 gp for the upgrade (8,000 - 2,000).

Your bonuses to hit and damage are incorrect as well. The masterwork +1 to hit is an enhancement, and therefore does not stack with the +1 magical enhancement. Your bow has +1 to hit (from the +1 magic enhancement), +3 to damage (from the +2 strength and the +1 magic enhancement) and it deals 1d6 corrosive damage.


Actually, there are several problems here.

First, Corrosive is listed as a melee weapon enchantment, meaning you can't put it on a longbow period.

Second, a +1 Corrosive Composite Longbow (+2 Str) does not need the masterwork. Masterwork is required for it to be enchanted, and so does not need to be noted there (though you must account for cost). On top of that, the bonus from being mastework does not stack with the bonus from being enchanted.

So you end up as such (should you be allowed by your gm to put it on a ranged weapon, as an exception)

Composite Longbow - 100gp
Masterwork - 300gp
Strength Rating +2 - 200gp
+1 Corrosive (+2 equivalent) - 8000

Total (as Rasmus said) is 8600.

That being said, the bow would give a +1 to attack (from the magical enchantment. The masterwork one does not stack). It would give +3 to damage (+1 from magical, +2 from strength). And then 1d6 acid damage on top.

If you want it to give a +2 to hit, you'd need to enchant it as a +2 Corrosive weapon (+3 equivalent), which would increase the attack and damage by 1 point each, but raise the price for that part from 8000 to 18000, for a total of 18600.

edit: Ninja'd by Tels, but leaving this post as it has additional info

This makes more sense. Thanks a ton!

It's listed under Ranged in the APG.


My apologies. I found it under the charts for melee weapons in the PRD, so I assumed. my mistake
