[Slam Berserker ] New Player Help

Build: https://poe.ninja/pob/5ee1d

Hello, I came back after a long time and this is my 1st build in a while.
Im having difficulty surviving in t16 maps with my current setup, bosses destroy me and I dont even get to see what caused damage lol.

Looking at other builds on ninja, ppl have less Effective Health Pool but are doing much more than I am and idk where the problem is.

Im guessing my fist upgrade should be the weapon, but I didnt bother with it because Im already 1 shotting pack mobs in t16 maps, survivability is the problem, or something else im probably just bad.

Any help is appreciated thank you.

There is a bunch of small stuff but nothing big jumps the eye in terms of survivability issues.

As you mentioned, your weapon isn't good. Try upgrading it.

Your cast when damage taken setup isn't good. Cwdt is usually kept low level because it's pointless if you have to take almost lethal damage before it triggers. Limit it to level 2 or 3 and adjust vulnerabililty and molten shell levels accordingly.

According to POB you are missing a passive point, probably from quests unless you just haven't allocated a point so far. Type /passives ingame in the chatbox to see which quest you are missing.

Your tree setup is inefficient. Rather than allocating the 2 str passive points on the outside near the blood magic and call to arms keystones you can just connect it with 1 str passive below the robust notable. If you do that you have enough points for nomadic teachings without further leveling. Should help with survivability.

Other than that, you don't have any eldritch implicits on your gear so that's a low hanging fruit. Capping your chaos res and increasing your armor are also steps you can take that should help. They aren't bad by any means but improving them might help.

Thanks for the help, il look into it!
