[LE] How would I make a weapon that does extra damgage to specific enemies?

[GeneralDuvais]

I was using the Creation Kit, but I couldn't find out how to make a weapon that does extra damage to specific enemies. How would I do this?

Make an enchantment or spell that is keyed to your specific enemies, then attach that effect to your weapon. I can't guide you through specific steps, but I would recommend looking at More Interesting Loot for examples. It has a number of weapons that are keyed to various races or actor types (undead, daedra, etc) using that approach.
