We haven't done a dagger in a while, if my memory serves. Plus, this one is made of stars.
Name: Fang of Oblivion (Wowhead, Thottbot, WoWDB)
Type: Epic Unique One-hand Dagger
Damage/Speed: 271-407 / 1.80 (188.3 DPS)
- +47 Agility, +54 Stamina, and a Yellow Socket, which will probably let you add to crit, hit or haste, depending on what you need more of, with a +4 Agility socket bonus.
- +1869 Feral attack power, so you can do more damage in your new kitty form.
- Improves crit by 29, haste by 24, and attack power by 80. So yes, this is a damage dagger all the way. Rogues get the edge (get it? "Edge"?), but anyone who can wield daggers and likes stabbing with them will benefit. Hunters, you could use it, but there's better stuff out there for you -- even dual wielding with something else, there are polearms that will give more agility and more stats you want.
Getting Rid of It: You would sell something made from gaseous balls of orbital fire? Oh, you would? Well in that case, a vendor will give you 23g 84s 13c for it (which seems cheap to us, but hey, you're the one selling it). Or it'll disenchant into multiple galaxies of space energy, all conveniently contained in an Abyss Crystal.
