So, dumb question. Once it gets to 'eat off your face with acid' level how are you supposed to counter it? Besides carpet nuking the entire battlefield I mean.

The only way I can see that would destroy them at this point would be nuking the whole place. This is why I always make it clear to tell when Victoire is beginning to set her rose fields, once they are too widespread it's hard to win against them. It's her main advantage on this RP, late game dominance, like any decent mage character.

That said, Zac could have won easily with his powers. Victoire isn't omnipotent, but against Machina she's really hard to take down. Bonesword bailing out was the worst move ever for them, since he was the only one not affected by the Roses, given that he's technically a Demon.

PS:

To put it simply, and in Windel's words: "People are stupid." The two only combatants with good chances of changing the game left the battle. Sad, but true.
