Something about playing as Minun & Plusle triples the Bossberts but it also makes the match end if 3 player deaths happen so the most feasible ways for me to win without losing any lives were that either one of my characters dies & Ranno dies twice or neither of my characters dies but Ranno dies 3 times. I think the only other way to win would be to kill all 3 Bossberts at the same time & then avoid the ground at the moment they all finish exploding so Ranno falls to his death without me & the match ends.
