does it works i dont have settler yet cuz i have been in sanctum , idols are really pricey and i was wondering how hard iss to recombinate idols like doing exiles one.

like gambling

i got lucky sometimes but i think on average it came down to the same prices as buying them
but my idols are not worth more than 1-2 div each, so maybe its worth doing it if you going for perfect ones

You need to farm a ton of gold for it.

Unlocking black market for idols is 100k gold.

Each idol is 25-35k gold.

Recombing the idols is anywhere from 30k-75k gold each also requiring two idols.

You could easily blow through 5m in an hour or two just sitting there buying and rolling idols.
