Diablo III: Reaper of Souls

The Templar and Scoundrel will be unlocked throughout Act 1 and the Enchantress will be unlocked at the beginning of Act 2. Please note that this trophy can only be unlocked while playing solo since you cannot have a follower while in a party. To unlock the trophy you will have to have them follow you when asked and if you said no, you can just go to town where they are standing then press to swap them out for whatever follower you are currently using until you have had all 3 with you.
