He was with a group of 30s and 31s. The 31s either sucked at holding sword or just didn't feel comfortable trying. He decided to give it a few shots. He basically had to have his super at least once per sword I think he said. Idk I was impressed too. He's a hunter so going invis next to crota deff helped.
Um I think it was only half randoms too. He was with a friend or two so yeah. It's possible... Just really hard lol
