If you would be so kind as to look in the stormreaver monument there is a list of all the upgrades epic reaver items will be gaining. Among a series of +8bonuses the epic versions of these items seem to have gained a +elventy7 to new nameage. Such as stormreavers tablecloth, i guess thats a step up from napkin...i guess.
Cant actually see the items tho, just the upgrades.
I have screenshots but that would be far too much work for me=p
