He should be fine. Ein said in the trial that their blood neutralises poisons. And later it was said it's because of their mana. I see no reason for him to not be fine. I'm just mad they didn't kill the guy on the spot. Why not use the mana stones to help Roselia recover while they make the antidote themselves? This is so stupid. They have no garantee that guy has the antidote nor that he will give it even if he really has it. And even if he gives, it could be a fake for the lols. And that all on top of Roselia might die before the villain feels "generous" enough to give the antidote
oohh you're right, it happened as you stated haha!!
Aw, I hope Carcius will still be alright even if he absorbs the poison in this way!
