PoE builds similar to PoE 3.20 - Ice Shot Totems - Mapping & Floor 4 Sanctum

Hi all, I am still very new to the game and tried following Iceshot build I saw on YouTube. So far mapping is amazing, but I'm stuck on on t16 Bosses and seem to be lacking burst damage compared to what I see in other builds. I would appreciate some feedback on how to increase my damage further! :) &x200B;

The life is lacking, couldn't find a way to bump it higher. Dps-wise looking fine, i guess with such numbers it is possible to freeze non-ubers and maybe it will be benefitial to opt for heatshiver, but then we will need to figure out a proper way to cast hydrosphere and i'm lazy. It is hard to tell budget, but i guess it is possible to get everything for under 20div at the middle of first week. Possible a lot less if you selfcraft some parts. Feel free to suggest possible improvements, i'm not good at building)

hopefully heatshiver doesn't get a rarity increase. made this in like 1 hour and have no idea how to level it lol. you need the 3.21 tree pob

Wanna try Ice shot, but couldn't find any builds. How trash is my first attempt at making a build? 1.3k hours and this is my first build.

I've been PoBing this build for a couple of weeks now and I think I've got a pretty decently optimized league starter tree+gear. 4 million pinnacle DPS with easily obtainable rares and no PoB warrior BS. No flasks except rotgut, nothing ticked that shouldn't be, etc, no additional curse, no influenced gear except a life % hunter belt. Fork socketed into 6 link. Ballistas turned off, guard skill turned off. Far shot estimated at 40 projectile travel distance instead of 60 (at 60 DPS shoots up to 5.5 million) With single target gem
