1. i've reached a poing in factions where i can travel to elona. If i do that, when can i comeback to cantha? Do i have to travel a lot so i can come back?

2. If I buy a skill from nightfall can i use it in factions?

3. Some skills from factions are diferent from those of nightfall(impale in factions is a spell that does direct dmg and impale from nightfall is a hex). If i travel from factions to nightfall wich version of the skill is used?

1. Instantly
2. Yes
3.No skills are different in the campaigns.

1. No, just click on the boat and pick the one of main port towns.

2. Yes, you can.

3. What? All skills work the same in all chapters. Is it different skills for different class? Maybe the only thing in common between them are their names.

The skill should be the same in any campaign. They change them from time to time so what it currently has as a description will be the same at any location.
