Empowered Moonkin

Empowered Moonkin was a druid Draenor Perk, available as early as level 92, though it was not guaranteed to be acquired until level 98.

Trivia

 * In the Warlords of Draenor alpha, this ability's name was Owlkin Fury and it was triggered by Owlkin Frenzy. By the time Warlords went live, Owlkin Frenzy had been removed, and Empowered Moonkin triggered on its own.
 * Coincidentally, when Empowered Moonkin was later removed, the effect it triggered was renamed to Owlkin Frenzy.
