Always wanted to see a room sector that was "underwater". I think all classes would be able to hold their breath for a period of time. Obviously fire giants are problematic, but, just like air sectors, there are always ways around it, whether it's a potion or item.
I think I started working on this at some point but never got around to fully implementing it. Still, would be neat to swim around shipwrecks, undersea caverns and hang out with the mermaids. Yeah. Mermaids.
