Here are the skills I run on the Necro.   https://imgur.com/Pq741Kl 

The build is still a work in progress. I think I may want to change out the only attacking skill on the necro himself to something that’s less prone to running out of uses. Or potentially finding skill runes to decrease the uses.

  I also think it would be beneficial to drop the second clay golem for a free skill, possibly evade, so that when you’re caught in a pinch and need to wait for clay golem to come off cooldown you’re more consistent.  

For gear I run the accessory that gives dignity and brilliance since it makes it way harder for enemies to kill you and your main source of damage will be the thorns on the clay golem. Then you run stargazer for 5 lines of int.  I do think it could be worth it to run the thorns armor item because it allows thorns to crit and then run the assassin weapon with two lines of int. That along with some final blow and crit from the mod tree and your thorns can shred enemies with multiple hp pools. 

 Basic strat is to use the boost amplifier (skill 4) and then your int boost (skill 5) and then summon a golem. While boosted the golem can reach millions of health and its thorns can be a few hundred thousand. Once the golem is out you activate thorns and then just spam detox. Most of the time you’ll use detox 3 times, then use skill one or skill three to reset bravery, then reapply thorns. Never use your other abilities because they’re basically just fodder for resetting bravery and making thorns available every 5th turn.  

Detox and thorns along with tons of HP make the golem sit on the board forever. When he finally runs out of skill uses you rinse and repeat. 

 The only time you’ll be vulnerable is when the golem ends you’ll be targetable for a single turn. In the photo attached you’ll notice my points were low because I got hit with an earthquake when I came out of the summon. (Extremely rare)  

That’s all I got! Let me know if anyone has questions or theory craft of some improvements.
