Piety or level 66-69 maps farming

Farm Piety
>Get lv66 maps from drops
>>Vendor 3 of the same map type to get a 67 map
>>>Make sure to do Chaos recipe whenever possible. Unidentified is better since 8/10 rings/ammy will be trash.

Repeat, and you'll either do those 67 maps, or return 3 of a kind for a 68 map. 68 maps drop much better loot compared to 66/67, so don't waste time on 66/67 (except tropical Island, I can clear that in like 4-5 min, and find that map the funnest). Piety is best for farming wealth however, since you usually should be be able to clear a whole run in under 7 minutes.

Stack as much IIQ/IIR, then go nuts, and hopefully RNG will be kind to you.

I always jump into maps just because I find it extremely tedious to farm 1 area over and over. If thats not an issue for you then Piety and late act 3 area's are probably better then 66-69 maps.

personnally i find that a full clear of lunaris 3 gives more xp and loot than 66-67 maps, but because i also find it really boring to just farm piety i usually kill her till i get 3-4maps, then do the maps, then repeat piety and etc.

i don't usually run 67's, i change them to 68's and run those when i get like 8-9 of them and then repeat the process.

after 72's or so i usually get bored and roll another character

For phat loot farm Piety until you can farm Dominus. Then farm Dominus.
Break repetition by running the occasional map you get from farming bosses.

Pretty much what I have been doing since I got to level 70.
