My witch is terrible

She was doing great for a while but now at lvl 74 my damage seems to have dropped off a cliff and I have a difficult time clearing anything but Tier 1 maps.

The build is something I came up with, golems and a few spectres with Eye of Winter (the new frozen orb skill). I then stacked a ton of minion damage % and got the notable to the left of templar start that applies all minion damage % to you as well. I thought it was a clever way to get 2 for 1 so to speak.

Anyway, she sucks now, both damage and survivability. I used to have zombies too, didn't do much. Is there any way to salvage it should I get a ton of regrets and make something else?

Hopefully that works

So it's a summoner AND a selfcaster?

Don't be offended but in order to salvage it, it would actually be easier to level up a new character - half the tree should be thrown here.

Best advice I can give is - don't create your own build from scratch. Pick a build - any build, literally any build - and then modify it to your liking. You need a lot of understanding of the game's systems to be able to handle anything past white maps. Especially in today's POE.

Real quick few pointers
- 4 link at level 74 is bad. You could easily buy a 5 link for very cheap.
- you are not CI or ever LL but you barely have any life on your gear, pretty much none on jewelry (less than 100 total) and literally zero on chest
- are you res capped?
- tree... oh man - the minor nodes near witch start - just no, you don't take them, you either pick one way that is either ES or Minion shit (or spell dmg/speed if other way) or better way just path through int nodes - these minor nodes have very little value and pathing through int saves skill points

I don't have a lot of experience with golemancer but you need a lot of currency and uinque jewels to make it good. Unless you have something really good (like a watcher's eye for instance or a cluster of course) investing 3 points for a jewel socket is not worth it. Discord artisan - no. Just no. This isn't a herald autobomber. And you also took practical application - I have no idea why honestly.
If you want to do a hybrid then at least pick hybrid nodes like Written in Blood and Melding, not to mention you have Heart and Soul right there and yet it's unalocated. And power charges - you don't have conduit from what I can see so they don't even apply to your minions.

Whenever you plan a tree make sure you at the very least have ~100-150% inc life if going for a life build or at least 75-100% if going hybrid.

As a rule of thumb when levelling try to increase your life pool by 300 per act meaning in Act 10 you should have at least 3000 life. It doesn't allways have to be like that (minion builds tend to require less for example) but it's a good thing to keep in mind for a new guy.

Like I said - at this point it will be faster to level up a new character, assuming you are a fairly new player it should take around 12-15 hours to get to level 66-68 and start mapping.
