Dúrin´s Axe

+30 OB, can cast any one spell from Earth Law, Locating Ways, or Direct Channeling 1x/day, may summon from 777' away, and does double damage (x2 hits).

Really, that's it? We are talking about the best item of the Dwarves and it doesn't even hold a candle to Elwe's sword. No, Durin's Axe should be a +77 OB (when in Durin's hands) that does all of the following listed above, and It should also be of Slaying orcs, trolls, and wargs, Mithril, and Holy.
