Build Suggestion for POE2 first timer

Witchunter with sorcery ward and full evasion its very tanky and you dont get hit all that much. You could go grenades which is very easy to get up and running and then use galvanic shards if you want. I could give you some old gear and divines if you want because im quitting the league.

Resurrecting minion summoner is a strong and safe way to experience the game initially

Go energy shield, maybe hybrid life es Use a scepter and wand or trenchtimber For skills focus ranged skeletons like archers, arsonist or lightning mages. I'm not sure what's best right now but arsonist felt really strong when I tried it out. Use skeletons from your scepter as tanks, and if you find your minions dying, you can throw in 1 or 2 skeleton clerics, but it's important to make your minions tanky too as they don't do mechanics and just eat it to dumb stuff. Also look at offerings and see which ones fit your play style

On gear focus minion skill levels where you can (scepter, helm, amulet, maybe weapon), then spirit, finally defenses (cap resist and get as much es or life + es as you can)

On the tree, try to grab increased es and minion nodes... there are 3 types of minions: Companions, Resurrecting undead, and temporary minions. Get stuff that helps minions in general or resurrecting minions

Avoid spectres until you are confident and comfortable with the build and clearing mid tier maps at least, as it can add a lot of complexity but can also boost your build a lot

Don't sleep on the Basic Attack for any of the weapons especially early on. Crossbow especially.
