Riven smashed all the undead into pieces. Spartacus did, but he took the glory as the master, and it wasn't that he just sat there. He was the one freezing the undead while Spartacus took care of them.
Besides, the energy he was using wasn't easy either. His body was covered in sweat, and it felt as if his head was swelling. Not only was he providing aura to Spartacus, but he was also doing so for the Grave Knight behind him, guarding his back.
But even when all the undead were smashed, the single funeral guy who issued the challenge still didn't appear. It was simply too much for Riven.
So he commanded Spartacus to start smashing the houses next and cut down all the undead in the village. "You want to hide? Well, what happens when there's nowhere for you to hide?"
That was the thought behind the plan. Riven was simply tired of playing the undead game.
