What build is best for Solo with MF gear

Can someone expound upon the mini-boss runs they do? Feel free to inbox me. I am curious also how people get to Piety so fast, especially as a summoner. I feel I am clearing the entire path to get there.

1: Run city of sarn for the corrupted zone. (10-15 secs per)
2: Kill the boss.
3: Hope for midnight drop
4: Sell for 1 ex

Repeat like a robot for days.

Try rathik's witch summoner MF build. That will be your cheapest best bet for solo MF summoner.

I currently run a 9 aura ele power siphon shadow with 344/46 mf in ambush. I can solo maps just fine with 82 all res(I use 2 andv rings as well) 2800es. I do die from time to time though as mini shav makes me have low es. I can run 66-70 maps no problem with 6k power siphon. The secret is fast attack speed and a 20/20 pierce....chain makes the skill to mana hungry. In group play I switch out lmp for gmp pierce for chain and ele weapon dmg for reduced mana. I also run conduit and give all 3 charges. Its quite a fun build and groups will love you :)
message me if you would like to see gear or build.
