Infinite Research: Heroic Greater Invasion Points

Once the Legion has sown confusion and chaos, then they will begin their real assault. Huge invasion rifts will open and the Legion will march forth in great numbers. The defenders, scattered to protect against smaller rifts, will lack sufficient strength anywhere to stop them. That is when champions like you are most needed. Seek out one of the Legion's major invasions and throw everything you have at it. Show the people that with enough determination you can cancel the apocalypse.
