People might have already put one up but i just got done pming a longish guide to someone, so here it is if anyone needs.

Mf Auradin:

Max these: Conviction, Resist Lightening, Resist Fire, Salvation.
Add one to zeal then rest into holy shield.

When making an auradin it's best to get uled because then you can max out the stats and have holy shield right away, if you do baal games max out conviction put one into holy shield then max the rest.

The gear is as follows:
Weapon-Hand of justice Runeword (Gives holy fire aura)
Armor-Dragon Runeword (Gives fire aura also good vs defence vs missle)
Shield-Dream (for lightening aura also GG resists if you have a 45 resist all 3 sock shield) Also gives mf
Helm-Dream ( Same as above)
Ammy-I prefer to use a cheap ammy (Saracen's Chance) because it adds resists attribute and iron maiden for the monsters fire and light immune. A maras or pally crafted ammy might be more of an interest to you if you dont mind the extra hrs/fg to get them,but note the skills wont add much damage seeing how the max damage for an auradin is 70,000.
Rings-Perfect nagels.
Gcs/Scs-Gheeds Gc and one Offencive gc (only one offencive if things aren't dieing right away) And mf scs (maybe some resist all scs)
Boots- War Travs or Waterwalks, If your having trouble in chaos sanctuary with those blasted mages living for the 2.3 seconds before they die, if not use perfect or near perfect war travs for resist.

I use a self-stacking method which i will now go into detail about:
If you want to mf alone this is basically key to be able to do it flawlessly. You can choose any merc you want as long as they can use a dragon armor and a dream helm.
Once you get those items for your merc (and weapons or whatever else you want. Sword+ shield for act 3 merc, bow for act 1) then you will need to simply take off the merc's helm and put it where your helm is making it so you take your helm off, now with your helm off put it on the merc and then take it off and put it on you agian, do this 50 times. Then do it with the armor. Each "Switch" of armor will make your auras do 1k damage more.

The reason why your auras stack is because you have 2 fire auras and 2 lightening damaging auras on, then you add one more on top and it makes a third glitched aura.

I hope this guide helped you.

anyone want to confirm this and give the man a cookie if it works

Oh also stats is pretty simple i forgot that just add str untill you can use weapons or armor, or use really weak armor with low str required and add the rest into life, You wont need dex for Block rate because nothing really hits you lol.

Also, it does work

I just tested that self-stacking method in SP and it appears to work.

Where do you mf? I would assume places accessible to walking such as pits/chaos. And how would mf'ing andy/meph/baal be done? Just curious.
Otherwise this looks like a great build, im making this next ladder.

tested it a little further and it appears that the stacked auras remain even if you remove both your items and reequip them, and even if you only have a single one equipped
potentially, you could drop one of your dreams for a 'better' item, like griffs helm


so if I were to use this on my Aurasorc, I could self-stack with my mercenary, then switch to griffs for more damage and keep dream shield on

Mostly pit, chaos, pindle then walk to baal ( i know its kind of a pain to walk to baal but the monsters there drop good stuff and its hilarious when baals minions drop instantly/near instantly.)

Also, a side note if something like black souls / pit lords give you trouble you have three auras to help becides conviction. Lightening resist, Fire resist, and salvation.

Because of the skill points added you will get 2 more max resist for fire resist from the fire resist aura, same with lightening resist, just from having them not just on.

I keep my merc's items so i dont have to find more dreams etc. But ya you got the idea.

Thats pro
I might just put a point into charge so i can run there instead of walking
