PoE Summon Ice Golem, League Starter, Slam builds

Hi Exiles This build has gone from volc. fissure totems leaguestart > conc. path totems to now this. Totems were fun for both builds, but now I want something that can speed run bosses/sanctums/harbingers and decided to go out of my comfort zone and try something unusual. I failed, like, every single sanctum on this melee build (I was the player making fun of people for failing sanctums when on my totems) but now with enough DPS Sanctums are easier now than they were on totems. The build is fun. I've never played a build where the defenses were to just kill everything before it kills yo

I wanted to play around with Warcries and Ice Crash was just pretty, so I've been working on this build since league start. Nothing fancy yet as far as equipment goes, Ideally a + crit chest and a ring with frostbite on hit would be a better choice, but I've only put maybe 2-3 Ex worth of currency into this build. Handles T16 just fine, and while single target isn't great, with a little work this could get up to 1m Shaper DPS pretty easy, at least according to PoB. Let me know what you think, and any suggestions.
