There are some alternative's to rift leveling like massacre bonus farming on Act 1 Halls of Agony 3 and the Act 2 Temple of the firstborne. Remake the game once or twice if you do not get any Look for a boss bounty (Zulton,Maghda,Azmo) Do not kill anything on the way to the boss, just when you get to the boss. Try for level 70 level reduced items(see Gear section) then store in stash Roll for a legendary with damage bonus from Kadala / Spreadsheet from u/AlexRaEU from season 18(Alex says he will update if anything has changed) Go back to seasonal character and set game to Hard unless you are plenty experienced then set to Master Take follower weapon or Check vendors in town for a weapon Feel free to check others suggestions in the comments for alternatives to level.
As Diablo 3 Is full of RNG and diversity in your classes there may be some strategy or order to the leveling experience that can vary for everyone.
