PoE Voidforge, Cold builds

I have been playing Wild Strike in the past and always had a blast. This league i want to give it another go with this build i made. I was prety shocked by the Voidforge prices though, so i guess i won't leaguestart with this. I'm unsure whether i should go with Grace or Determination. I also don't really know what other skills i should use so i made a CWDT Blade Vortex thingy to create power charges. Feel free to give me some suggestions

The PoBs are all for Lvl 100 because i got or got pretty close to lvl 100 last leagues, so i usually do only lvl 100 PoBs for myself. But if you are not complete new to this game you should know how to delete some points for a lower lvl tree ;) First is a Full Unique build using Ice Crash as damage source. Using Voidforge in combination with Elementalist to be reflect proof, Death's Door for Bleed Immunity, Cyclopean Coil for Shock & Freeze Immunity: Same as a Totem Build: Then we have a Curbebot, because i like playing Suppo

I had a cluster jewel drop with the vengeful commander notable on it and thought it could be interesting to use in a build with all 3 auras and all 3 elemental damage types on wild strike. here is what I have planned so far although it probably could be optimized by someone better than me. Also the cluster jewels are what I've already got to work with. Any advice before I commit to this would be fantastic.
