Forum:Stamina Leveling

Alright so, sorry if this is in the wrong place or whatever... but yea.

I'm a new player, and I started with mage... then went to sorc. I just now found out that you can take 'augments' from other vocations and use them on any other vocations. So my question is, does this feature carry over with stats as well? Can I like, play as a ranger to increase stamina from normal leveling... then switch back to sorc and have the extra stamina?

Does this work with any stat?

Are there a maximum base stats you can get from maxing out each vocation?

Also, when you buy a vocation with discipline, can you switch to the other ones you've already bought for free?

Thanks :)
