Hello there!
You can farm the lovely charms in the island expeditions. You get quite alot and I don't thing its supposed to dropp any since the mobs don't count for the "test your strength"-quest for the darkmoon faire. Per nhc expedition you get about 1-3 lovely charm bracelets. I dont know if there is a faster way to do it but since its a "bonus" I guess it belongs in here. If not, please remove it.
