I once had a mod I don't have now. I liked it, but now I can't recall its name. I would really use some help with finding it.

It was a weapon upgrade mod. It lets you upgrade weapons by battling the "weapon guardians" in the magic arena. You choose the weapon you want to upgrade, push and hold a button - and you are not in Cansas Cyrodiil anymore. There are several Guardians, or howtheycalled, who look like ghosts, atronachs, zombies or spriggans. They are named like Guardian of Price, or Guardian of Charge, or Guardian of Damage, and so on, they are very strong and immune to magic.

I tried searching "Weapon Upgrade" or "Pimp my weapon" but found nothing. Help please?
