Well, Runewords can't be used on Rares, Magics, etc. so that idea is out of the question.

If that was pre-patch, its Godly, but kockblocker is right, Rares overpower that so much now, that it is nothing more than a semi-decent weapon to use at lower levels until you find a phatty Rare, or something better.

Great spawn on a Magic though!
