**I did NOT come up with this build. Just something I saw and looked fun and interesting to play last league.**

Got bored last league and wanted to give my self a challenge.

Ran this build last league and it was great.
Started the build with a tabula, atziris foible, and a storm prism. All other gear was purchased/crafted using the profits made by the build itself.

Its fast, tanky, and doesnt care about degen or hits.

The basic concept is taking damage (degens + hits) and converting it into lightning damage, increasing your max lightning res + max chaos res, and then taking that damage and reducing it even further via Mind over Matter + Divine Flesh.
The Font of Thunder, a surprisingly cheap shield, and two Shadowed rings are how we convert 65% of both fire and cold taken as lightning damage, then an additional 50% taken as chaos via divine flesh.

Cold Damage Taken

This means we take 0 fire and 0 cold damage.
This also means we take everything as either phys, chaos, or lightning damage instead. However, the mind of the council helmet takes 30% of lightning damage taken from mana before life.

Between Cloak of Defiance and Mind of the Council we have a 70% MoM, then plus the Hierophant ascendency point (divine guidance) we have an additional 10% MoM making the total MoM 80% Damage taken from mana before life. Adding in a Watchers eye with clarity %Mana taken before life and I had a total of 88% Damage taken from mana before life.

Damaging Hits

This clearly means we need to build Mana, and this works perfectly with The Agnostic keystone.
The largest downside is, since we use Kaoms Spirit gloves and they have a mod that removed life regen, how do we regen our life?
Well, the agnostic is not considered life regen/recovery and is excluded from the downside of Kaoms Spirit.
The upside is we get permanent Rage Regen and can use this for our own benefit from either keeping the rage or dumping it via Berserk.

Overall I give this build a 9/10 if you want a single character for both mapping + bossing.

If anyone wants to know anything else, or has questions. LMK.
