So I’m doing a hunter x hunter dnd, and I’ve been thinking of adding a special sort of power at nen level 20 (you don’t need to know the details basically nen levels are a thing) that differs depending on your nen type.

The only thing I have solid for is emission. When an emitter reaches nen level 20, they can emit their nen to wherever they want, regardless of distance, as long as they have been to that location. I was wondering if you guys have ideas for other non specialist nen types that offer a similar level of power? For transmutation I was considering making it so they can change the properties of physical objects rather than just their aura
