*rubs chin* Weird, I'll look into it. The ring wouldn't bestow water breathing in either case, but it will halve damage from water-based attacks (like the turret crawdaddies). In fact, there are no item that will let you breathe underwater. You could always buy the bikini (if I remember correctly, Keith has it), it gives you normal mobility underwater (but doubles the damage you take), and since the entire underwater area is based around you moving at half speed, it should make it a lot easier to get through. Also, have you noticed hitting a block underwater will release an air bubble? That's not just for show, those will restore your air meter if you catch them.
