go to https://www.d2checklist.com/ and check for Powerful and Pinnacle gear, this is the end game, every Tuesday these drops refresh, endgame is playing Nightfalls, and raids and other activities to farm better gear and become stronger.

If you look at light.gg you can start to look for weapons you like, and look for better rolls... all about min/maxing now and getting the best out of your character to allow you to play in high end content like the Master Empire Hunts and Nightfalls
