Role changes:
The Reset Adventures option CLEARS your role history. Example:
Let us suppose your role history is Mage -> Warlock -> Paladin -> Ranger. You are a ranger and you cannot return to the Warlock or Paladin role.
Reset Adventures. Now, you are a ranger only. The fact that you were a warlock or a paladin is forgotten. Therefore:
1. You can become a warlock or a paladin again.
2. You will gain "full levels" immediately. The restriction "only 1 HP and skill point until you reach a level higher than your highest level so far" is forgotten, too - because there is no "highest level so far" after Reset Adventures.

Reset Adventures returns the game to the very beginning but your stats, skill levels, traits and inventory are unaffected ecxept for SOME quest items, which are removed from your inventory. Is it bad? Quite the opposite! The world is full of monsters again so that you can gain levels in your new role quickly.

Always reset adventures after a role change unless you have a serious reason for not doing it. Examples:
1. You are far in the game and you want to continue. You don't want to begin from scratch.
2. You have reached high levels in the guilds and you have changed your role because you want to train high level skills quickly - you will gain levels quickly so that you will be able to train in the guilds often. Reset adventures after the training.
