Tbh more like scholars light, but anything that gives eldritch can work.
Any time 
Can you make a video??
It pains me to see Fire Strike maxed out and no points in ulzuinās chosen :<
Unfortunately no.
I dont get it? What exactly is correlation between FS and ulzuin chosen?
Fire and Physical
I think you should check again skill description of ulzuin chosen, it does not affect fire strike
btw where are the videos of your build mate ?
Read few posts above, mate 
Ulzuinās chosen does not affect Fire Strike
i am wondering if viper + cof can stack?
^yes Viper and CoF resist reduction stack. however the focus of this build is chaos damage so the RR from CoF doesnāt help muchā¦ the slow is helpful though.
iāve specced some points out of CoF and into flashbang instead, i feel reduced DA is better
Thatās my issue with chaos damage. Itās such a pain to get resist reduction. Hellfire mine should be great but itās such a pain to use. I rely on exterminus and witchfire. Physical is far easier
Its not such a big problem. manticore, eldritch fire, harbinger (from weapon), solael flame (from component in weapon), augment = 30 flat, -50% and 15% rr. Its solid even without HF mines.
JoV what group you sided with? The Order or Keymon ?
On elite with Kumon, maxed rep, stockpiled augments and on ultimate changed to Vigil.
But you dont have to do that if you dont want. Augment vise you need one 7% aether 10% lightning armor augment from Vigil, so you can take Vigil from start
Have you taken this into crucible yet? Can it handle Gladiator?
No, I dont like crucible and dont play it much, but I think that with this amount of tankines it wouldnāt be hard to handle gladiator.
Ulzuinās Chosen only affects Grenado and Canister Bomb right? Why did you put points in the skill?
I didnt grim calc is screwed up. I will make new one.
No point in making new one cuz it continues to be screwed up. Ill update first post with ss of skill distribution.
