53 BM hunter just solo'd. She happened to drop the Blade of Eternal Darkness and the Charstone Dirk, both of which are pretty useless.. unless the Blade works on arcane shot/steady shot, then the mana regen might be pretty nice.

And no, that isn't a typo. I am lvl 53


UPDATE: After a little testing, I think it's safe to say that it does NOT proc off arcane shot. QQ, I now have a worthless dagger that some warlocks would pay quite a bit for..
