Hi my gamertag for Nintendo switch is Atw622  and I was wondering if someone could help me finish my 3rd conquest so that I can finish all my seasonal challenges, so far I have finished both the Divinity conquest for reaching a level 75 greater rift solo and the Years of War conquest, I only need one more and was hoping for help in finishing either the Curses! Conquest or Boss Mode conquest, please feel free to add me as a friend my username for Diablo on my Nintendo switch is Atw622
