Arcane surge on Assassin's mark is a placeholder for arcane surge coming from the cluster jewel. With Overcharge, Shock nova can shock for 62% a pinacle boss. The pen supports with vaal storm call are just here to simulate the "ignore monsters resistance". If the gem duration is too low to support a new use, maybe use a 24 charge soul ripper and rely on the 6 souls gained by 2% life dealt to unique instead.

Since the other dude is asking for more PoB, here is a tentative Lightning Conduit Elementalist. I looked at the other lightning conduit PoB and found it extremely lacking. Insane custom multiplier from everywhere, a shock calculated on the basis you have already a 100% shock on the target which it obviously won't, a need to alternate between lightning arrow and lightning conduit, an idea that using voltaxic make the build reach "a much high ceiling" while you are basically giving up weapons and ends up with a spell doing 40% lightning 60% chaos (very fun to scale the resists after that), etc

Before the leaguestart, I planned a build around Stasis prison, before finding out how rare (and expensive) it would be. I'm still leaving it here in case it could help someone getting inspiration, since I don't believe I will be able to buy it this league, the next one, or ever. It's basically a build based around both CWC and CWDT. Basically, you run around using cyclone (because it's smooth). Bonus point if you use stampede for the base 150% movement speed even during cyclone. Cyclone is linked to CWC and forbidden rite. So e
Since I left the league and Stasis Prison price promises to be insane anyway, I'm leaving a build concept around Stasis Prison.
