Loved how most of the episode is spent on the hype build up. Like when the scales are introduced it becomes pretty apparent that they are going to be used and that Aura won't like the results. But we really spend time on why Frieren hides her mana and why it won't ever occur for demons as a valid long-term strategy. And so by the time the scales come into play we are absolutely hyped for the result. Which is followed by immediate and complete dismissal. Frieren has no interest in demons besides killing them. Even when presented with someone pretty high in demon hierarchy, Frieren does not care for any information or giving any orders, besides killing them as soon as possible.

Also that decapitation scene is just great.
