Enchanting the enchanted (3.5)

[Ahab]

Recently one of my players asked if he could get a certain enchantment placed on his already magical sword. Is this possible? If so, how much should each one cost based on their respective modifiers?

Not sure which edition this is for:
[EDIT]: Well, the thread title was updated. 4e advice still stands. :smallwink:

4e: No. You cannot create, for example, a Flaming Frosting Sword +1 from a Flaming Sword +1. You could create a Frosting Sword +1 by dis- then re-enchanting it, or by using the Transfer Enchantment ritual (I think). You can kind of go from a straight magical weapon to a specially-magical weapon with the same process, but "Magic" is still a unique weapon enchantment type.

3.5: Yes, but there's some math involved.

Take the effective enhancement modifier for each enchantment (e.g.: Flaming is a +1 effective enchantment). Add the modifiers of all enchantments on the sword (e.g.: Flaming Frosting Sword = +1 +1 = +2) and add them to the base enhancement modifier of the sword (e.g.: A +1 Flaming Frosting Sword = +1 +1 + 1 = +3). Calculate the cost of the sword as if it was a straight enhanced weapon (+3 sword = 18k gp). Some enchantments have straight gp costs; simply add these to the final price after performing the above calculations on the other enchantments.

2e and earlier: No idea
