Keep farm lockeds and stash them and sell them in helloween event you will make eassily 1m by saving 60-70 lockeds
Or go in nprmal rengol maps farm them- insignias,jewels,and pinks( some pinks still worth 100k+)
This is the better option for farming now days
And you can run arena if you can afford lots of anks and pots cause vials are now 160-170k
And chance of loot them is like 1 in 10-20 chests.
You need atleast 1-2 ankh kits for running arena so it will be equal to the vial price
Better run new maps normal
