Obviously not scientific but could be useful:

Snowchipper is 4 weight and 20 delay (and runs out the stamina after ~2 minutes).

Also throughout all the pages I am noticing after the cap is exceeded (100 or 120 or 130) the only negative effect of stamina is no longer being able to jump (primarily bad when in water because you are unable to jump out of the water at that point).

Regarding swimming and dying, I remember doing the burning rapier with my gnome rogue and taking just this side of forever to find the damn bottle at the bottom of the ocean. If you needed stamina/endurance to stay afloat, I'm sure I would have drowned, along with most of the other rogues.

I also remember spending all sorts of time swimming around akanon looking for hidden passages and such when the game first released, and the only thing I had to worry about was air.

Technically the yellow bar that everyone keeps calling the stamina bar is actually your endurance and not stamina.

It originally was a Stamina bar. It changed to an Endurance bar later.

More misinformation than an old allakhazam discussion: a classic p99 thread.

These things decrease stamina:
* swimming
* jumping
* auto attack (lose x amount of stamina based on weight each swing)

These things happen if stamina < 100
* cannot jump
* str decreases, possibly encumbering you.

These things happen if stamina = or > 100
* cannot jump

Therefore, if you're a melee and your sta is over 100 invig spells are pointless... all melee should be over 100 sta so invig spells have always been pretty pointless. All that you're possibly gaining is some lost str.

Notice that loss of stamina never did/does/will affect attack speed or make you unable to attack (lol if p99 is your first time playing eq please stop contributing to conversations thx).

Well, if you say it's true without providing any evidence, it must be true.

Right now it's called the Endurance bar. :D

Thought the OP covered that!

Pretty much, yeah.
