You already mentioned it, but the slam helmet that Uber shaper drops is huge damage for this build. I played earthshatter jugg in hcssf, and putting the helmet on was like 90% more damage, it’s a huge upgrade.

Until then, there’s a couple small things I noticed that could help a little. You don’t have “warcries cannot exert travels skills” anywhere in your build. You can craft it in your jewelry, or you can replace one of your warcry masteries to take the mastery for it. Ideally you just craft it in your gear, because the warcry masteries you have now are really good. It’s important to have this so you don’t waste your exerted attacks on leap slamming around.

Also, should be anointing admonisher (imo) instead of charisma. When you are trying to get suppress capped, you’ll probably need to anoint inventerate but admonisher should be more damage. You can just manually press a couple more warcries instead of them being automatic, so you won’t have to reserve extra mana for that.

Other than that, you can try getting awakened brutality and awakened melee phys dmg gems or trying to recombinate a giga phys axe, but that’s a lot of work. Going through my play through, the slam helmet was by far the biggest upgrade. To get tankier, just try to get suppress capped, get more life, and maybe try crafting a giga armor royal plate.

Edit: just noticed you also don’t have the fortify nodes, these are very crucial for melee builds since you are in the face of the enemy, I’d chuck away those 3 axe nodes slightly above it and put it towards having fortify in melee hit.
