Video: Riven "without using Traps or Abilities" but I used ability and completed it.

"Synthesis a Simaris target without using Traps or Abilities while having Hobbled Dragon Key equipped alone."

I used Excalibur ability 2 multiple times, and challenge complete successfully without a fail. Either the game fails to detect Excalibur ability 2, radical howl, or the challenge text is wrong and is ok to use abilities.
