Weapon Enchantments

[PepsiWhirda]

Hey, I want to get a weapon enchantment from the elves.  It's only going to last for a handful of posts and won't have any effect on other players, just on undead NPCs.  Would I have to pay for a full move if I'm only going to use it 2-3 times as sort of a "smite undead" type thing, and then never again?

Something like:

Smite Undead:  Whirda's kukris are enchanted with the holy power of an elf priestess.  Whenever she deals a blow to an undead creature, the attack deals extra damage.  Whirda can will her blades to flash with holy fire for a period of 5-10 seconds, during which attacks will disintegrate undead flesh.  This enchantment does not affect living NPCs or other primes.
