Drop some non combat emission hatsus

So, I was thinking about pros and cons of each category and I came up with a few good non combat abilities for some of the categories. However, emission is a tricky one for me. I couldn’t think of anything that isn’t either an energy blast or something like Knuckle’s APR( combat hatsu).

Share your personal emission abilities that aren’t combat oriented. It would be desired if the ability is an everyday use ability.
