Profession Changer

Profession Changers are NPCs who can change a character's secondary profession. They will only offer to change your secondary profession once you have ascended and fulfill a one-time requirement for each secondary you want to be able to switch to.

When changing their secondary profession, the player will lose access to all of his skills for his old secondary profession, and in return be given the "basic outfit" of skills for his new secondary, unless this is not the first time you've switched to this new secondary profession. Any skills you may have already aquired for your previous secondary profession will still be available to you should you choose to change back, including any Elite skills you have captured. Also, your Ranger pet will not be lost if you choose to not have Ranger as your secondary class. It will still be available if you choose to change back.

Prophecies
In the Prophecies Campaign, there are six profession changers (for the six core professions). Each of them (except the ones corresponding to your current professions) will offer you a "'s Path" quest. By completing the quest you will be able to change your secondary profession to that one by talking to any of the 6 profession changers you have completed quest for.

Factions
In the Factions Campaign, there is one profession changer, Senji, who charges a one-time 500 for each secondary you want to be able to switch to, he does not charge for those that you have already unlocked with the the Prophecies Campaign profession changers.

Nightfall
For the duration of the Guild Wars Nightfall PvP Preview Event a profession changer has been added to the Great Temple of Balthazar.

Any PvP characters and roleplaying characters can change their secondary profession here, but the new Nightfall professions are not available for roleplaying characters.
