I've been trying to do something similar by attaching the shocks spell visuals to armor with no success. I'd love a tutorial! 

I don't have a lot of time right now, but basically you need a .nif with an AttachT node. That's an NiStringsExtraData node called "AttachT". The Value should be "NamedNode&", plus whatever the name of the bone you want the nif to attach to. Here's one of my rotating cuffs as an example.

Then you want an ArtObject of type MagicHitEffect that points at that nif file

Then set up a Magic Effect that uses that art object as Hit Effect Art

I don't think it needs the Light archetype unless you're planning on attaching a light to the nif (if you do, that's what the AttachLight node is for). You probably do want Constant Effect since this works best as an enchantment or an ability. You need delivery = self and you need the FX Persist box ticked.

Then set up an enchantment using the effect

And attach the enchantment to a an item of armor in the "Enchanting" slot

And with a bit of luck, that should attach the effect whenever the armor is equipped and remove it when the armor is taken off.

You an also use the magic effect to define an ability and add it to a character by whatever means, then the spell will attach the nf when it runs and remove it when the ability is removed.

Hope that helps

Cool, really appreciate the walkthrough! I'll play with it and let you know if I have any success 

Great job explaining everything! Everything worked flawlessly first try aside from something on my end with my nif, it seems to have lost it's billboarding and it no longer draws over the other armor parts properly. I'd hate to turn this into a nifskope troubleshooting thread lol, so I'll just thank you for your help thus far!
