What is the best way to get the Avarice conquest?

I found this on reddit, link

This is a quick guide covering how to complete the Avarice conquest (50 million gold streak).

This method took me one attempt and I had room for another 10-20 million. It goes without saying this is done on T6 and you will need boon of the hoarder. Mine was 28.

Gold find: 9000% ish. Sun keeper, Gold skin, Leoric's with emerald, paragon and 80% amulet should help you get there but I did it without Leoric's.

Where to prep: Ruins of Corvus and the area that connects with it.

You will need to run around getting as many scarabs (and other mobs) spread throughout Ruins of Corvus. Do not kill them yet as the gold piles will despawn over time. Make sure there are several monsters right by the stairs because you will need to keep the gold streak as you change maps (it lasts for around 3 seconds).

Prepare the other area the same way. When you reach a dead end you will start to back track while killing monsters and getting the gold as you move along.

Take your time: Don't pick up every pile as they drop. Make sure there are monsters ahead before picking everything up.

If you can't see any, grab 1 pile, aggro a couple of scarabs in between populated areas, go back, pick up another pile to maintain the streak and then kill the scarabs. This is not about speed, it's about coordination.

You will need to be quick when transitioning from one floor to the next as you have 3 seconds to zone in, kill some scarabs and pick up another pile.

Should you try this, good luck!

I know this is an old question, but I'll add my two cents.

Probably the easiest(and most time consuming) way to get 50 mil gold streak. I did equip some gold find items, but they don't seem to have (much) effect on the cache drop. Anyway, I collected 110 caches(including bonus caches) and opened all of them together.

This gave me 57 mil gold(around 1:55 in this video).

Of course, as l I said in his answer, if you face a Gold Baron while hunting bounties you can get this conquest there, but even if you fail you can still just continue collecting bounties.
