Hi everybody,
It is possible to have your follower during diablo's fight.
In order for him to join you, you have to do :
- Be in a party of 2 people and you clic on the portal to diablo.
- Your friend doesn't accept to join the fight and leave the game during the little cinematic.
- After he left, the game will ask you if you want that your follower joins you or not.
- And voila !
And a pic so it did happened !
