Read the title. This is technically a successful run without Gear or Abilities, but it doesn't get anywhere near close hitting the 10 Round limit. I managed to do it with the other Mythic fights, but it just doesn't possible with my specific account, with the specific characters I have available, though maybe players that have high Portray Ezio + the full Poison team can manage it?
I'm not too disappointed by this. I'm actually pleasantly surprised that this mode doesn't really need Gear or Abilities. So long as you have some specific characters (Ezio, Euphoria Marcus and Euphoria Pickles) to counter some specific enemies and fights, everything is basically doable. Even this is technically doable, you just won't hit all the bonus rewards.
