I'm feeling pretty meh on this chapter overall. Even discounting how disappointing Clayman was, what was that fight with the lich? Sure it's not a weekly series, so it's harder to justify time to any one minor development, but this whole encounter felt very forced and rushed. It had big "Everyone clapped" energy. The story is being stretched too thin right now, too much is happening at once, so it's all watered down and less satisfying than it could have been. Maybe the light novel is better about this?
