PoE ArbitraryElk builds

I am trying to make some kind of trickster build leveraging CI, Aegis, and Iron reflexes to stack a ton of armour, block and max res. My attempt thus far is using lightning trap for damage but I don't know that this is the right direction. I can only crack about 1 mil damage (I think it would really be at least 2 mil thanks to nimis) but I am hoping to get a bit more. I don't know how well POB calculates lightning trap damage so it could be a fair bit more. I would guess so far this build would cost about 50 div or so but it is hard to say. [
