There are ways you can breathe underwater.
1. Have a cleric cast the spell (I believe it is called 'underwater breathing'
2. Have a necro lich or ghoul you (so you don't breathe).
3. Be a nereid.
There is an interesting area called the temple of last breath where there is no air. It's empty but fun
If you say plz because it is shorter than please, then I will say no because it is shorter then yes.
