Probably gf barb since the other option got patched
This is the only answer you needed.
The others who posted didn’t understand the question or were simply unaware of that exploit that is now fixed.
IF it was still possible to do, then the answer would have been option 2.
I used to run a very simple script that was just moving mouse and clicking between 2 coordinates to abuse this exploit very fast.
It wasn’t using image detection or anything that normally gets people banned.
That was an easy 10m igg in 5 mins, whole floor filled with piles of gold, then I would manually gamble and pick it up from the floor around the merchant.
But yeah… now your only option is a GF barb.
The gold per run is not a good performance indicator tho… if you want data that has any meaning, you need to look at gold per minute.
