Would it be better to magic find in nightmare on players 7 settings or farm what I can handle in hell on players 1?? (Single player)

If you can handle p7 in act 5 nm, should be able to handle hell andy and pits.

Probably p7 on nightmare, but a mix is good.

Hell

as soon as you mf in nightmare you remove the ability for any item to drop.

always do hell, depends on your character too, personally if i was a blizz sorc (which is what most mfers are without enigma) then i would farm mausoleum/crypt on whatever difficulty players you want to
no immune to colds in there and they are all zombies/skeletons so they wont do much harm. even if any mobs spawn with deadly combinations like fana/might and extra strong/extra fast for example

Thanks guys, been doing Andy/Mephisto and stony tombs in hell on p3 I found arachnid and a coa!! I’m a orb/fireball sorc
