I think Flamme's point about needing to be a mage of a peaceful era to defeat the demon lord comes back to the idea that magic must be perfectly imagined to be made real. If a mage can't properly imagine a peaceful world then they can't fully imagine defeating the demon lord because that will create a peaceful world. If a mage can't imagine defeating the demon lord they will fail to do it. In the battle with Denken, I think she got that close before blasting him so she would be suddenly in his face, shocking him so he would be surprised and freeze just enough to delay his casting a defense spell. I also think that his use of an area of effect spell, his combo fire/tornado, was to force Frieren to cast a complete globe of defense magic around herself. As she said while training Fern, this would very quickly drain her mana, much faster than Denken would drain his just using attack spells. That's why it's what he did after saying he needed to end the battle quickly. He just didn't realize how huge Frieren's mana pool is because she always hides that. It makes mages overconfident just like it makes demons overconfident.
I see. I didn't think about defense magic's mana cost because I thought he's also using his mana in the tornado but I guess if there was anyone else but Frieren they might drain sooner than tornado I see the point for sure!
