[3.1] Crit-Based Storm Call Cascade Inquisitor with Inpulsa's - looking for guidance!

I've been playing my crit-based storm call with inpulsa's into maps these last few days and it's been pretty rough getting into tier 4 and higher with my current set up.

I think survivability is a big issue for me at the moment. I'm even having some problems sustaining mana with MOM and mind of the council.

I think some key things that I need to focus on are some leech and maybe speccing towards some life nodes. I am concerned however that I'm going to sacrifice a bit too much damage to get there.

The character is Hrungus_McDungus. I know there are a ton of people that have been using similar set ups and I probably should have done a bit more research but I dove into this, but was having a ton of fun with spell cascade.

I would greatly appreciate any advice!
