Toskk's Maximized Wristguards

Source
This item can be found inside the Deathbringer's Cache after defeating Deathbringer Saurfang in the 25-man version of Icecrown Citadel.

Trivia
This item was named in homage to the Feral druid player Toskk, who built a community around his online Feral DPS Gear Calculator. Toskk no longer plays, but during WotLK his calculator was updated by various members of the community and had been used by thousands of Feral players over the years.
