Just wanted to give this spell a shout out since I know most people don’t even have it on their bars. It totally negates the breath/bubble mechanic in the underwater delves.
It’s especially good if you’re doing them in a group because it’s a pain to share bubbles or cycle such that no one is in danger of drowning.
Just wait until they change it so you need Azerite Infused Air, something only granted by the bubbles, to not drown in those instances. This is a joke I could see actually happening.
I ALWAYS use underwater breathing, even for silly stuff for herbing or swimming 20 yards to a cave entrance. I hate holding my breath and it gives a swim speed boost.
