What the first dude said

Hm....I don't think I will have an attack to compress or expand either way.

Prefer Attack Compression

Punching. The impact point where you hit

Stabbing. The impact point. Bullets. Impact point. Laser, literal compression of the laser until it slices everything. Make something infinitely sharp.

How about making a huge plasma sword and just compress the thing because it's an attack. Somehow. Compress it until you don't want to and just throw and let it explode.

Ngl I'm picking Attack Expansion. Either go big or go home.

It hits with the strength of an ant crawling on you everywhere. Maybe even weaker.

I understand the value of range, but sometimes you have to be tank in certain situations.

Imagine dropping a nuclear bomb lol

That's a beauty for sure.
