Give me your item and the money to pay for the enchanting. I will visit my buddy in the royal palace (not telling you which one) and have him work on it. it's way better than any work you will find done around here but with all things there is risk.
Combining two of these is not impossible but would increase your base cost by 1.5 for each enchantment thus multiplying the final cost.
1d6 extra is 5000
for every 1d is x10 for every d6 is Triple
ex. a 2d6 is 50,000 while a 1d7 is 15,000
while a 2d7 is 65,000
a 10d20 would be 710,000
this applies to all enchantments that follow
Specific bane: A weapon with extra damage against an enemy of your choosing
Flaming: shrouds the weapon in flames, does not hurt the user
Frost: shrouds the weapon is ice, does not hurt the user

Shock: Shrouds the weapon in crackling electricity The electricity does not harm the wielder
Unholy: imbued with the power of evilness and cookie thievery, this weapon cannot be held by an good person and deals extra damage to persons of good alignment
Keen edge: reduce critical threshold by 1
ex. a 20 would become 19-20 and a 19-20 would become 18-20
15,000 for the first and double for every 1 extra.
ex. a weapon that went from 20 to 15-20 would cost 480,000
Speed: allows a weapon an extra attack in a turn
the first upgrade is 30,000 and every extra is x3
ex. a weapon with 4 extra attacks would cost 810,000
