So, I want to do a custom bound weapon spell. Yes, I intend to use Harkon's sword as a template because I had the idea of a sword forged with the blood of the PC's enemies. The sword behaves like the original product (drains health, magicka and stamina), therefore the spell itself only works (or works best, at least) as a vampire.

If you use it as a vampire, the spell is toggleable and safe to use. If you use it as a mortal? You must kill people if you don't want it to drain YOUR health/magicka/stamina with the possibility of killing you.

With that said, I have a few questions:

-How do I make the CK work with Dawnguard's assets?

-How do I create a bound weapon spell?

-How do I make it toggleable?

-How do I make it scale with the character?

I might have more questions, but let's call it a start.
