While farming for the Mystical Source (legendary crafting material), my templar accidentally hit the Diablo piñata and this dagger dropped. I loaded Adventure Mode Torment level 6, and clicked the dagger.
To my surprise, it was the Horadric Hamburger ramped up to level 70, which pops in my mind … will all level 60 sets make a return as a level 70 version? Chances are that’s the drill.
