It looks like Blizzard's warning that things might be a bit more "broken" than usual in Diablo 4's patch 2.0 Public Test Realm was valid, because mere hours after going live, it's been discovered that you can hit level 60 in just 20 minutes.
In a game like Diablo 4, you're definitely not meant to be able to do that, but content creator and streamer Raxxanterax has demonstrated the entire process in a video on YouTube. It's thanks to some broken Stronghold mechanics currently in the action RPG's PTR, which Raxxanterax shows off at the Omath's Redoubt Stronghold in Kehjistan.
