PoE Lightning Coil, Hex, Bossing builds

I'm a sucker for perma flasks and wanted to try hexblast mines (seems like it will be good for sanctum and league mechanic which is what I want to do) so I made a POB for it and it kinda looks good. - feel free to steal and modify if interested or provide feedback on why it isn't very good. Not a league starter but something to transition to day 4-5 pretty from poison exsanguinate/PC - You could make the swap at 85 if you really wanted to and had the reservation and flask cluster jewels, 91+ and it would start to feel a lot better. 6-7 mil DPS on a first week

On ssf standard. Wondering if i should create a build around both of these or drop one. Most people I saw on ninja were only running one or the other. If I run both i am thinking about putting an aura set up in staff for lvl 7 enlighten. With both I hit dot cap rather easily, but I might struggle with defences a bit. I want this to be a bosser. So mainly wondering how i fit in more defence. Main things i can think of is purity watchers eye and progenesis. POB (Just something I threw together quickly, needs a few more things) &x200B;
