[quote=@Fading Memory]My personal opinion on them, Ink, since you asked is that the pressure manipulation seems a little vague with what you specifically mean for it.

Can she just outright crush other divers? Make their suits implode? Push them away in an uncomfortable manner? All of the above? It's just a little unclear.

Or I'm too used to using an overanalytical way of thinking and it's way simpler than I'm thinking.

It is a little vague, yeah, but that’s kind of the point for me – detailing some specific abilities and just speaking on them in a general sense. I didn’t want to list it like a bunch of stock abilities like it was a video game since this is a collaborative story of sorts. 

As for what Marina [i]can[/i] do? I don’t think Marina can outright crush other divers, no, but I do think changing the pressure around them to make them sink a little faster or get pushed back further by the momentum of the tides is more of the wheelhouse of her capabilities within that particular ability. You have to think within the scope that Marina isn’t a child prodigy so her power threshold is probably a little bit smaller than others.
