I have a better tip and without wasting time fooling around, since blizzards don’t do anything against them and everything is clear.
Make a sorceress, download a bot and make her run around opening chests in act 3, getting the easy HRS, filling herself with items and getting bored with the game, doing nothing.
In the Battle.net app, with D2:R selected, click the gear next to “Play”, select “Game Settings”. Check the box for “Additional command line arguments”, a text field will appear below, add -resetofflinemaps to the text field.
