What are some of the quickest treasure troves to get to nowadays?
Hallowed Hill is stupidly easy to run to but there’s not a 100% chance of it spawning there. (There is a small chance of TWO spawning there, though, unless they patched that out.)
I just checked it and i have 2 Treasure troves spawning at this moment.
Arkovian Undercity has a decent amount of heroes and troves.
Only one trove will spawn there per game session.
Prospectors trail portal , mountain deeps trove , quickest trove I use .
You can run that trove at least 3 times compared to 1 hallowed hill .
Just ran hallowed hill for the first time mind and 0 troves , don’t know why you would even run that . Just for the chance at 2 when other places are faster 
As for me i prefer Mountain Deeps. It’s quite fast + you can farm heroes for Ancient Hearts
…What? Hallowed Hill is really, really fast and easy to get to. I mean, yes there’s a chance of zero troves there but for the time and effort spent (read: hardly any at all) it’s a no-brainer to run if you’re doing a trove run.
