Respawn endlessly at floor 200 with Hunter Mythic, or the Perk and/or Shrined Perk. Only run forward to the shrines that are right in front of you (if they aren't, reload) and kill them with Luck maxed (with Epiphany the better) and Nadroji.
Fastest way to kill epic enemies which can drop Mutiny/Ragnarok/Insolence.
This is how I finally got my 2 Mutiny Gauntlets.
