So at first lets look on items globaly
To be able to solo act 1 without worrying to die much you shoud aim for 20k hp and 150 all res. After you achiev this focus only on damage.
Now lets look on some equipment:
Boots:
I personaly dont feel that movement speed on boots is that much important so i iamed for higher dex insted of movement
You can choose from this filters:
15+ MF, 150+ Dex, 10+MS
18+ MF, 200+ Dex
price shoud be around 400k igg for both.
Pants:
16+ MF, 100+ Dex, 100+ Vit shoud be worth around 300-500k igg.
Chest armor:
16+ MF, 100+ Dex, 100+ Vit shoud be worth around 400-600k igg.
Belt:
16+ MF, 70+ Dex, 60+ @res shoud be worth around 200-500k igg.
Bracers:
16+ MF, 80+ Dex, 60+ @res shoud be worth around 200-400k igg.
Helm:
30+ MF, 70+ Dex shoud be worth around 300-600k igg. But look for higher base MF and worse socket because you can allways change socket later for more MF.
Shoulders:
16+ MF, 80+ Dex, 80+ vit shoud be worth around 150-400k igg.
Gloves:
16+ MF, 160+ Dex 30+ % Crit dam 200-400k igg.
Quiver:
16+ MF, 80+ Dex, 80+ @res shoud be worth around 100-500k igg. ( look for other stats and pick the best one ofc bonus crit c is good aswell )
Amulet:
30+ MF, 80+ Dex, 80+ vit shoud be worth around 400-600k igg.
Rings:
15+ MF, 80+ Dex shoud be worth 300-500k each ( dex can sometimes go even around 120 for same price if you are lucky so look around for best ones )
Weapon: Crossbows works much better than bows here so i suggest you to make filter of blue xbow for 250k igg dps shoud be around 1150 dps
So to count all your stats:
Dex around 1250+
Vit around 550+
MF around 220+
@res around 120+
For price of 4m igg which is quite cheap.
Now for follower:
pick cheapest weapon called The Three Hundredth Spear shoud be around 350k pick some extra cheap rings with 10 MF for 20k both
25 MF and some shield for low price aswell
Now you shoud be able to solo act 1 easily.
My favorite MF run is start with A1 Q9 part 2.
Teleport to the festering woods there clean all rares and both caves.
After that move to Cemetery of the Forsaken there clean all three crypts. In this part you shoud
Than move to Leoric manor go back and kill the pack in front of entrance to manor.
And finaly port to Halls of Agony Level 2 and proceed further till you kill butcher. This usualy nets me around 2 - 3 full inventaries of magic/rare items.
Later after you make some money from this and you want to ugp your gear aim only for 20 MF armor parts first with same or better stats that you have right now.
Well thats it for now. I hope i was able to help you.
