PoE Shadow builds

I'm working on Scion trapper. Arc Traps for farming, Lightning Spire Trap for single target. This is the build I'm using: Path of Building: I thought about Scion, cause it should basically work the same after taking Path of Shadow node, later just respec points used to get to Shadow area. Then we have easy access to Scion's life wheel which allows to modify base tree a bit and do not take hybrid Life/ES nodes, bu

Build: I used a level 19 Storm Call linked to trap to represent the hits from a level 20 Lightning Spire Trap, and I used a 22 Bladefall to represent Seismic Trap. Trap Support (Used to make the mockup skills) is losing its More multiplier so the damage numbers listed here might be a little bit off, but not by a huge margin.

I've fallen in love with ED the past few leagues and decided to theory craft this build while waiting for incursion to start. My inspiration for it was the instant cast of both contagion/ED as without cast speed this interaction feels pretty bad. Here's the pastebin for the build, imported direction from in-game - Skill gems and links are included in PoB. Bandit rewards is kill all for the 2 points. Unique items are the following: 2 Poet's Pens, 6L "The Perfect Form", Chaos Impresence Amulet, Atziri's Step (+1 frenzy charges not needed, I also prefer th
