Hey everyone. I'm a huge self-cast enjoyer, and LC especially. I've build a bunch of LC characters in different ways and this one ths the strongest so far.
I don't see anyone doing this build so I might as well put my findings out there.

So, the benefits of this build:

• Great mapper, T17 viable
• Simulacrum farmer (you can just stand in wave 15 and not die)
• Uber Boss viable (I've done several of them so far, build is not a bosser but it just has so much raw power)
• Immune to shock. freeze, stuns, poison, curses, bleeding, corrupted blood, burning ground.
• 85% max elemenal resists
• 88% attack block, 91% spell block
• Great recovery via ES and Life leech
• 20+ million DPS
• 1 million EHP (with Immortal Call on, half of that when it's off)
• Cold damage component which helps us chill and freeze enemies.

Cons:

• Sensitive to map mods. Cannot regen, cannot leech, avoid elemental ailments (can reach up to 100% chance with atlas tree) = bricked build. Less Block - technically can run but you won't enjoy it.
• Expensive on the high end. The showcased build is worth around 450 div. I built it from zero though, this was my league starter.

Main mechanics/Important notes:

1. You have to reach 65% shock, there are many ways to do it. I craftred boots with 60% increased non-damaging ailments to free up some points on the tree. 2 or 3 Overshock nodes on clusters are very helpful, they can be found on Large Lighning and Medium Non-damaging ailments clusters.
2. Glorious Vanity and Corrupted Soul keystone are important parts of her defences, She leeches both life and ES, and if you lose them at the same rate, both of your leeches are doing work for you. Glorious Vanity is also a great way to find attack and spell block nodes.
3. Svalinn is totally OP if you build around it. I use Safeguard cluster on the tree which provides +5% max spell block, This is absolutely insane. I use Ice Nova of Deep Freeze and Ball Lightning of Orbiting with Culling Strike. Ball Lightning provides a ton of life leech, that is why I use it, Note that I have Crusader mod Life per Enemy Hit on my ring.
4. Shavronne's Revalation is amazing ring on this build. I was using Clarity before, and this ring allowed me to skip Clarity entirely, freeing up more points on the treee and allowing me to ditch Enlightnen Gem as well. ES is also very valuable on this build.
5. The Body Armour that I am using is self-crafted (as pretty much every item I wear), the main stat on it is Frenzy Charge on Hit. I don't see any other reliable ways of generating these charges. Most of the game I was using Expedition's End before I was able to craft this armour.
6. This build uses Controlled Destrution, so you need to make sure you have enough crit to sustain Elemantal Overload. If you don't use CD, you don't get full value out of playing EO
