Thank you for the shout out. Unfortunately couldn't watch it on stream.

So I've transitioned away from 'The Bringer of Rain' but afterward I realized I lost endurance charge generation. I've done some research and I'm triggering Warlord's Mark in the same link as Immortal Call and it seems to be working but if you've got a better recommendation on how to generate endurance charges I'm all ears.

Only other way I can think of is using Red Dream/Nightmare jewel and put it in one of the various jewel slot near fire/all res. To be fair Endurance generation from BoR is pretty lackluster to begin with so that's why it's not mandatory for the build in any way. However Red Dream/Nightmare is a fancy jewel to have.

The Red Dream is just fine, no need to seek the extra block value from Red Nightmare since the build isn't focused on block chance.

During my research I did come across the Red Dream and came to the same conclusion that the Red Nightmare wasn't worth it. Even the Red Dream at 120-125c is quite expensive. This is the skill tree extension of yours I could see supporting that Jewel. If it curled around to Diamond Skin then that's 41% to generate an endurance charge on death. If no Diamond Skin it's still very good at 26%.

On the other hand, the life leech/ from Warlord's Mark adds to it's value and I'm certainly generating a lot more than one endurance charge at a time now and much more frequently. I'm unsure if cast when damage taken is triggering Immortal Call or if it's triggering Warlord's Mark again. I'm reading up on gem ordering and looking into it.

As far as my knowledge goes CWDT proc at the same time. So the same moment you proc Immortal Call u will proc your curse.

Here's mine stuff (RZabc character)
I want to buy legacy void heart. Is it worth or just take common version? (also will buy witchfire brew)
Rerolled character today (from explosive gladiator with BoR + Jack + Soul Taker and like this build more) so run t10-14 maps only (and dying sometimes :))
I am confused by the presence of vaal gems. Auras pretty good but trap, how should i use it(or change)?
How can i improve character more? I would be grateful for any help.

Legacy Voidheart beats everything for a melee phys character. Common Voidheart even with good bleed and poison roll is still not worth it I think.

What I can think of is to change Death Oath to a better armor, preferably one with 100+ life roll if possible. You also don't need bleed immune flask because of Brutal Fervour. For that, if you wan't more damage simply use Witchfire/Taste of Hate.

Vaal Lightning Trap is very good for boss fight, or just tough monster like 4,5 essences mob. Just throw it down at the boss and it will pop, creating a shockground that will keep the mobs in shock while standing on it. 50% more dmg is quite crucial if you want to kill guardian.

You might also want to slap some uber lab enchant on your gears.

Better ring could also be an option. Steel ring for damage will always be recommended given you can provide enough resistance from other source.

Why even crit? You don't get Power charges, nor use Diamond Flask. Even with 6 power charges and flask, your crit would be like 60-70%. What's your current crit chance? Don't you waste so much DPS in this setup? You can use Added Fire and spec ouf of crit nodes for more life / damage.

I have close to 50% crit, with diamond flask that is effectively 70%. Crit is possible due to the fact Varunastra provide a good amount of accuracy so going RT would be a waste compare to the melee crit cluster right next to it.

Like I said in OP non crit is also ok but I would prefer that with Soul Taker. People have tried it as well.

If you want to have more damage just use abyssus, or get crit multi amulet with phys roll.

With conc right now, with a normal BoR i have 280k dps buffed. Including 200k from warchief totem thats pretty ok for the level of gear I have.
