Secondary Proffession

In prophecies, after you ascend. You may change your secondary profession. Well, I have a prophecies character, and I would like to change his profession to an assassin or a ritualist, where should I go to do this?

First, you can only change your secondary to Assassin or Ritualist if you have bought Factions and it's attached to that account.

To change your secondary to Assassin or Ritualist you can go to the Great Temple of Balthazar on the Battle Isles and use the secondary changer there. The other option is to go through the Factions or Nightfall storyline and use their secondary changer as Prophecies doesn't have a method for changing to A or Rt.

Where would that place be in factions?

The place is Senji's Corner http://wiki.guildwars.com/wiki/Senji%27s_Corner
