CDexWard: I am about to grab this game during the sale, along with the freshly released expansion. Ever since being obsessed with building a perfect character in Diablo 2 back in the day I don't like it when it is not possible to redistribute points. I already researched GD's respec options, do I get this right?

There are four kinds of stat distribution that is done by the player:
1. Attribute points
2. Devotion
3. Skill points invested into skills
4. Skill points invested into the mastery bar

And these are the means to respec those points:
1. Attributes through a potion which is a quest reward in the expansion
2. Devotion through a potion that is randomly dropped
3. Skills through a NPC
4. Mastery Bar somehow in the expansion

Is this correct? Can the potion for resetting attributes be obtained more than once? And what exactly resets the mastery bar?

So, is the only thing about a character build that can not be changed the choice of masteries/classes?

CDexWard: Thank you very much for your replies!

Another question I don't want to open a seperate thread for: Does is matter which mastery I chose first when creating a dual class character? Is there any difference between starting as soldier and taking up shaman as a secondary mastery or starting with shaman and choosing soldier as secondary class?
