When a champion uses Horrific Howl on a champion with Deflect or that has been targetted with Divert, and the attack is redirected to the champion that used Horrific Howl, the Horrific Howl champion cannot be attacked until the fear times out. The exact scenario was some Pirahnid was affected by Divert from some Circadian, and a M0untain Lion attacked the Pirahnid and hit itself with Horrific Howl. The next turn the Mountain Lion couldnt be attacked by any of the nearby champions (Pirahnid, Circadian, Mirevixen).
