What am I doing wrong with my build?

What gems should I be running? / talents should i reroll to.

I am having a hard time keeping mana without having to use 2 mana pots as well as being very squishy.

Supposed to be a cyclone shockwave slayer, but I know I dont have a staff that is strong enough yet to put shockwave on.,

updated, I have max resistants now 40% chaos, and I updated my tree. Now I need to figure out my gems I need to use, like determ, pride ,anger or what ever, No one has said anything yet that would be good to use.

Anytime I see or hear "what's good to use" I have to remember that "good to use" in this game is relative.

In other words, you should be using whatever gems give you enough damage and defenses to do whatever content you are primarily farming.

If my goal is to do T17s and pinnacle bosses, my build reflects that.

If my goal is to do T16s and other easier stuff, my build reflects that.


Minus mana can be taken on the tree with masteries and notables or you can get jewelry that does it.

You have to kinda pick your gems and balance your mana around all of that.

POE has a high ceiling in terms of "the best" there are mirror their pieces for any slot but that require giga levels of currency to achieve and often legacy gear.

Your phys mitigation is too low for my taste. I would respec the upper part of the shadow tree and put those points into more life, armour and take Iron Reflexes:

To alleviate the mana problems a bit, you could spec two point into Thrill of Battle, but I'm frankly not sure where those points are supposed to come from, as you're streched pretty thin already.
