Well, buggers is runnin' all around Azeroth with they's Charm Collector's Kits, ripping pieces off of everything they kill lookin' fer bits they can use fer ta make charm bracelets fer the powers what be. Now, I can see Varian or Sylvanas goin' fer such doodads, but to Tyrande Whisperinyerear really want a bracelet made of wolvar teeth and murloc toes? I dunno; power do weird things ta buggers.
I gots ta say, though, that the idea of turnin' pieces inta jooleries ain't a new one. Vyprania be the team's grand master joolcrafter on the Alliance side, and she been doin' such fer a long time. See them three danglies hangin' off her left ear? Yeah, they's all pretty what with the gold and thorium figglries and the black pearls, but when she started they was the index fingers of Noth, Gothik, and Grand Slam Faerlina. That necklace Phoenicia's wearing? Made from Hakkar the Soulflayer's toothies. Prince Keleseth's thighbone got scrimshawed down inta some real purdy chopsticks fer me ta eat me Chineses with. Galertruby shoots craps with dice carved from Keli'dan the Breaker's broken skull. In a different style, Vyp's got Moragg's big middle eyeball all shrunken and preservified and encased in plastics hangin' from a chain on her right ear. This bein' a family blog and all, would be impropers fer me ta tell ya where Ellspeth wears Instructor Razuvious' similarly treated 'nads.
So, go pry the teeth outta that dead ghoul and make yer bracelets fer yer 'chievements. Just keep in mind ya can put a little more efforts inta it and get ya something really unique.
