I've been following this for the last two days or so.

I'm highly interested, to say the least, but I'm struggling with picking an element.

So I'd like to propose a few sub-element ideas.

Ice? I'd assume starting out would be a slight chill around the character, and eventually building up to taking moisture from the air as stuff and freezing / unfreezing it.

My main argument is that early on the ability would only be able to freeze shallow water at best.

Would be a sub-element of Water.

If that's not alright, I'll happily come up with other options.
