Got some protips for people who don't mind "cheating," or would otherwise like a bit of a "safety net" for certain dice rolls:
The game does not autosave when you:
Enchant items
Open Horadric Caches
Gamble blood shards with Kadala
Start a game in Act 1 and you'll immediately trigger a checkpoint (and autosave). After the autosave, do stuff. If you don't like what you got, hit the Guide/PS button and close the game app from the dashboard, then start it and reload. You'll have all your stuff back.
Using the method I described above, I got one piece of Akkhan's in 7 minutes, and the next piece (completing the set) in another 40 minutes. That was rolling 235 shards every 2 minutes, so, effectively, about 4700 shards.
Thank you for the tip, man!
I do not judge you as a cheater, at all.
This is a glitch, much like the Grimoire glitch in EO:U.
If anyone has issues with THAT glitch, they might just need to redefine "legit" as "demonstrably insane".
...and I just might use it, considering the shite drop rates on console for things like RoRG - especially considering the new, improved drop rates on PC.
