Quick question about the corrosive roses, are demons affected by them? I want to know so I can act accordingly.

Considering that they are an effect of demonic corruption, no. On the previous battle Victoire was draining the blood of the ground troops to power them, that's why they took damage, but just their essence shouldn't damage other demons.

That's to say, don't touch the thorns, they'll hurt anyone who touches them and are strong enough to rip steel.
