I was thinking, because I read a post about Elliott struggling with spicy food, and I was thinking how good is Firen at handling spice. I won't bother you with a long process of thinking and lots of "This is not bad, but isn't it copying of Elliott too much? I should think about something more original." and so on. But eventually I cane to this conclusion.
He doesn't have the worst tolerance, but once it's too spicy or too much spicy food at once, he used to get sick. Now he has some tolerance so he doesn't get sick so often, but he definitely threw up when he was first trying heating spell.
Yeah, this is all I wanted to write. Have a great day whoever you are reading this. And if you have any more questions, you can ask in inbox. Have a good day.
