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 temporarily 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.

Core
Any PvP characters and roleplaying characters can change their secondary profession at the Profession Changer NPC in the Great Temple of Balthazar on the Battle Isles. The profession changer charges a one-time 500 for each secondary profession you want to be able to switch to. He does not charge for those professions which your character has already changed to before, and does not charge to change the secondary professions of PvP characters. PvE characters must be must be ascended or Weh no Su, or must have completed the quest Building the Base: Prisoners of War. Campaign-specific professions require their respective campaigns.

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 only 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 him or other profession changers. Senji is like the core Profession Changer NPC except that characters must be Weh no Su to reach him, he cannot be accessed by PvP characters and he only offers core and Factions professions.

Nightfall
In the Nightfall Campaign, the secondary profession changer is Zuwarah, he is located in the Command Post outside of Sunspear Sanctuary. He only appears after you complete the quest Building the Base: Prisoners of War. Prophesies characters must still be "Ascended or Closer to the Stars" to change their profession here.
