So I've tried going through the various tutorials that are available, but I've found nothing that pertains to bound weapons. Unfortunately, I'm also having trouble applying what I learned from those tutorials to bound weapons as well. Basically, what I want to do is combine the bound weapon spell with the lightning spell so when I do weapon damage with a bound sword, it also does lightning damage (Much like combining spells in Oblivion...which was built into the game at some point).

If anyone can point me to a tutorial or explain how I could accomplish this, I'd appreciate it.

look at the bound sword spell find the bound sword item copy it.
Look at a sword that does lightning damage.

From there on it should be easy to figure out

Bound weapons are actual weapons called out by the Bound Weapon spell, so adding shock damage to a bound weapon would be as easy as applying a Shock Damage enchantment to the weapon.

The existing Bound Weapon spells can give you a pretty good idea of what you'd need. The weapon called by the spell is determined by the "Assoc. Value 1" in the magic effect. That points to a regular weapon within the Weapons category, and that can be given enchantments like any other weapon. Copy the existing Bound Sword, add a shock damage enchantment, then make a new Magic Effect (or copy an existing bound weapon effect) that calls your new bound weapon instead of one of the defaults. Then make a new spell that uses that magic effect.

If you want the spell to work with Mystic Binding and give you a more powerful weapon, you'd need to create a second weapon with more base damage, a second magic effect that calls that stronger weapon, and apply that effect to the same spell with a conditional that chooses either the weaker or stronger one depending on whether you have Mystic Binding perk. Or just copy one of the existing Bound Weapon spells and edit it so the conditions will already be there.

Thanks, I'll give your suggestions a shot when I get home!

Not sure what I did wrong, but I now have the animation for lightning on my hand while I grip an invisible sword

Any suggestions? I'm totally failing here, probably because I'm more of a visual learner and all the mods tut videos I've watched haven't done anything to make this process click. To reiterate, I just want to cast the summon blade spell and have it do lightning damage in conjunction with everything else it does.

And on a tangent, this would be way easier if they just released some DLC that lets you mix spells together.
