PC on this stormbow...

what the stormbow is now: req 9 max dmg 10/7 sundering +22 fort
what it will be after i mod it: 10/10 sundering +30 fort

can you please tell me how much it is worth before and after? unfortunately its not 15^50, or else it would be perfect....

also, can i get a pc on these 2 (both gold and max):

reinforced buckler- req 9 tactics -2dmg while hexed +22 hp while in stance

poisonous cleaver of shelter- req 8 lengthens poison (duh) +5 armor vs physical +13% dmg vs hexed.

THANKS!

stormbow - no dmg mod=merchant
buckler - merchant
cleaver - 3k maybe/merchant would be easier

people dont buy stormbows without 15^50? thats messed up! least i didnt waste my money yet. ill keep it for myself. thanks for replying so fast!
