Exsanguinate/Seismic Trapper help request

Good morning. I am following Big Ducks' build guide, and I *think* I am pretty close to his gear in his pob. However, I just keep dying now from every single ground effect, among other things. The defense just does not seem to be there.

I swapped over to a Righteous Fire build, and I am crazy tanky and loving that. I went back to the Seismic Trapper recently and I can't make it through any map without dying at least once. I find this incredibly frustrating, and it is preventing me from playing it, let alone leveling up any more. Granted, after playing RF for so long, I might just be too aggressive in my playstyle. Still, I am looking for a way to beef up my defenses on this build without losing a ton of dps. I tried switching to a shield, but I still did not see any major change in my toughness. Any suggestions other than just adding more life, which is a little hard to do without changing ALL my gear, which I worked hard to get to this point?

Or should I try a different seismic trapper guide that is a lot tankier (and which would that be)? Hoping to be able to keep most of my gear and not drop another 10+ ex into it.

Thanks in advance for any assistance.

Here is the guide I am following:

Here is my pob:

And here is the shield I tried (might just not be a good enough shield to make a difference, plus I had a few different items at the time, so I needed the fire resist when I last tried it; I don't think the block/recovery is the thing that I am suffering from, I think it is an overall damage reduction issue because ground effects seem to be more painful to me than just combat):

your determination gem is only level 7? you need it 20 or 21 so u can get the max out of armour
i recommend dropping grace maybe and go for purity of elements so u get 100% ailments avoidness,and you must know that trappers need to cast and keep moving never stop while mapping or bossing just drop them and move out

I would just copy the build from the gauntlet event that every streamer is playing atm. Plenty of public profiles and basically they use same tree without clusters and with like 7k life.

Not sure how expensive the gear is tho but except the weapon and amulet they use mostly decent rares with spell suppression and life.

Im surprised that theres not even 1 active guide for sesimic trapper sabo build while so many people still playing it.

Maybe it got too old at this point and everything was written already?
