Superior Bound Armor?

[Truffinator]

Looking through the sight i found this spell and it said it was found in superior bound armor tomb. I was just wondering if anyone knew where that was or anyother way to get the spell. My newest character is almost full conjuration and my armor is really bad at the moment.

I think the database is wrong. It says this is in the core game, but I think you actually have to have the "Spell Tomes" plug-in from Bethesda. This adds spell books to the random loot you can find on NPCs and in containers. Activate the book and you can add the spell it contains to your spell list. And that's the only way I know of you can get Superior Bound Armor.
