Leap Slam - How to handle Physical Reflect?

In your case it might be different, though. Carnage Heart alone DOES have the potential to prevent the user from one shotting himself, but this requires a balance of gear and passives, a balance which the OP does not have. As soon as you shift more towards one or the other (dps or tank), your character suffers a bit. The more you go to the extreme, the more your character suffers. There are of course ways to fix this to some extent, but you will remain gimped.

Current Gear (I swap the Reduced Mana and Blood Magic Gems after casting the Auras)
I now run 7 Auras (Anger, Wrath, Hatred, Determination, Haste, Grace, Purity) and have 85% All-Res, 44% DMG Reduce through Armor and 69% with Endurance Charges.

I replaced Conc. Effect with Added Fire Damage (Lava Lash only gives 130DPS...) and my Unbuffed DPS now is 5.4k and with Auras it is 7.6k. So I lost around 2.3k DPS by replacing Conc. Effect with AFD. I say 2.3k because I had 9.9k DPS instead of 8.5k with my "new" 7 Aura Setup and by replacing Conc. Effect I went from 9.9k to 7.6k DPS.

At least I can now jump into Phys & Ele-Reflect Packs without dying, but 70+ Maps now take significant more time.

P. S.: I know that I should divine the new Boots and still need to replace the Gloves, Belt & Chest, but I am still searching for some good (I don't mean cheap) pieces.

Still say Hrimsorrow gloves would have been best option instead of replacing Conc Effect.

Will now test Hrimsorrow Gloves, didn't wanted to buy one just for testing but meh... Want to get this working with the Marohi Erqi.

Tested the Gloves now on a few Maps and they work pretty ok, still a lot of Phys. Damage that gets reflected but I heal enough to survive that now.

Will try it now with that setup and if any problems occur I maybe write them down in here.

How are your gloves not even 20%ed.. ?

Way too many unique items taking away from all the life/armor you could have on that gear

I just bought some cheap gloves to test them and my resistances are still capped...

I don't go much for HP on my Items because I plan to buy a Kaom's Heart when I get my Marohi 5 or 6L and I have no survivability issues. The only issue was the reflect and that is solved so why should I stack HP when I have no survivability problems at 2.5k HP and plan to buy a Kaoms?

I tested playing with a Kaoms and no HP on other Items and I won't have any survivability issues when I will switch to Kaoms.

If you really want to be able to handle reflect (even on default), just pick up a few more hp nodes. As a Marauder, there are a ton really close that are super cheap to get (namely those up near the Templar start). Honestly, using an Erqi, you can handle sacrificing a bit of damage for more hp. In the long run, since you can be more aggressive, you'll do more damage (seeing as you won't have to leap slam out as often).

I would shoot for something like 6k hp. This should not be difficult to get with a Kaom's and a bit of hp on gear.

I think something like this should work:

It gives you 175% increased max hp, meaning that after Carnage Heart, you'd be at 155%, giving you 2.5k from Kaoms. With 57 points used, you should be somewhere around level 45. It also includes the Templar ele damage with weapons, area damage, and Inner Force.

Maybe someone see's some HP nodes that I didn't grab and have in mind that I will use Kaoms as chest.

I think this might be a bit better for you currently.

I spec out of the melee phys damage at the marauder start and into some armor and evasion down in the duelist tree. Since reflect is affected by your mitigation, this should help you out with that. Also, I don't think the marauder starting points are all that efficient for damage, especially with the amount of strength you already have.

Edit: For your end game build, I found a pathing mistake near the templar tree. I also took the 8%->12% in the duelist tree instead of 2 of the 8% in the templar area (I actually ended up specing into one of them at the end again since I saved you a point with the new pathing).
