For my (probably) last build for Archnemesis, I jumped on the Cremation bandwagon, and I have to say it doesn't disappoint.

As someone who usually plays 'kill before it kills you' type of builds, this feels incredible, and I will most likely not go back to squishy builds any time soon.

I self crafted all rares myself, and spend way too much currency on gloves that are pretty much outperformed by Hands of the High templar for a fraction of the price.

Overall I am incredibly happy with the build, and if you are looking to farm Simulacrums, this is probably the build to go.

Edit:Some things I might want to add here:

If you don't run Incendecent Heart, the 'phys taken as ele while affected by Purity of Elements' mod on Watchers Eye is useless.
The 'ES gain on hit while affected by Discipline' is mandatory.

Save on gear, and get the alt quality gems instead. Your damage is shite if you dont have Phantasmal Cremation.

Getting Unearth to level 30 is your utmost priority. You can save currency on many fronts, but not on this one. Hands of the High Templar are a good and (a lot) cheaper option to crafted gloves.
