Champion Objectives

What para level should I be to complete Destroyer of Rifts, 6 minutes To Save The World and Guardian Of Sanctuary ? I tried to join a public game and got code 316502 whatever that is. I’m running my Necromancer para 393.

You just need to be able to solo GR75 so you can join public T16 rift games.
The rift speed quests (including the conquest) happen there on their own as soon as there is a decent open map.
