Drake Fang Talisman

The Drake Fang Talisman is an epic trinket that gives an increase to attack power, chance to hit, and chance to dodge. It is well suited for DW Warriors, Rogues, Feral Druids or Hunters. It's considered one of the best DPS trinkets even at level 70, and used by players well into Black Temple or Mount Hyjal.
