In both instances she can stay underwater as long as she wants without penalties of any sort. In Bloodstained: Ritual of the Night, Miriam can swim underwater via jet propulsion once she gets the Aqua Stream directional shard, or simply move underwater normally once she gets the Deep Sinker skill shard and has it active.Which is good, because the game can be excruciatingly difficult otherwise, and we really don't need more than that, now do we? Amazingly, he will stay under the surface as long as you want. Sometimes, he even has to fight enemies down there.

Ninja Gaiden II on Xbox 360 sometimes requires Ryu to swim through tunnels.Dizzy has no problem diving indefinitely as long as he's carrying a snorkel.By virtue of having all of one room with water, no one in Castlevania: Portrait of Ruin even needs an artifact to stay underwater indefinitely.Nathan in Castlevania: Circle of the Moon has this attribute, except that instead of grabbing a holy snorkel, you just have to purify the water.He takes the same damage from a puddle as he does when 30 feet underwater, and the lack of oxygen appears to be of no concern. Justified because Alucard is half-vampire and, as per traditional folklore, running water is hazardous to him. After this, you can stay underwater as long as you want. For Castlevania: Symphony of the Night, Alucard takes damage simply from touching water from the beginning of the game until you grab the Holy Symbol, which looks suspiciously like a snorkel.Also in Castlevania: Order of Ecclesia, once Shanoa has a Serpent Scale, she can move and breathe freely in water instead of floating up.In the Castlevania: Chronicles of Sorrow, the bonus characters have no real reason for why they can breathe underwater.While in the real world, this equipment would allow you to swim only a small depth under the surface of the water, in the games following this trope, it lets you plunge boldly into the deepest oceanic depths. Sometimes, the character gets a diving mask equipped with only a snorkel and absolutely no oxygen containers. This incredible feat is never ever explained, or even mentioned as something out of the ordinary in these games. This seems not to be the case with some Video Game characters, however, who can swim underwater for infinite amounts of time and show absolutely no signs of discomfort. The world record with training is 22 minutes, but anything significantly more than that would push the body to its breaking point. Longer than two minutes (without training to hold your breath beforehand) usually results in unconsciousness (and you'll automatically start to breathe again, which is very bad if your head is underwater). We can hold our breath for a short time, some of us longer than others.
