Game Mechanics: Underwater Stamina Usage

[Nokio]

Hi,

First time post in here so I am sorry if I am doing it wrong.
Im a level 42 shaman and only class I ever got this high level.
Played on live around Kunark but never made it past level 20. So I don't remember much from then.

As I level more and more I have been wondering what the stamina bar was for aside from jumping.
Never really looked much into it.
This morning I was looking at this page : https://everquest.allakhazam.com/db/item.html?item=2024
As I was reading the comment, I saw a post from 2002(Search for stamina). That post was saying that while underwater, stamina bar goes down. A Tips is to bring a shaman so he cast the stamina regen spell. (A Spell I never had to use so far)

I was wondering if this was worth posting here and decided to come post it.
