Ok here a question for you theory crafters out there, I notice most people use Blighted Marrow rune( 500% base damage–15% increase damage for every enemy it passes through). Why not use Blood Spear (650% base damage–extra cost 10% health). If you use the skill Grisly Tribute(10% heath on every hit) and have a good hit and regen, you don’t even notice the health cost. Any ideas on this, i mean thats 150% base damage increase.
Presumably because 500% + (X * 15%) is higher than 650% if X is big enough, i.e. you’re casting into large packs of mobs but I’m sure there’ll be some people along shortly that’ll say so if this isn’t it.
I see what your saying ,but from my experience that doesn’t happen much. You would have to hit ten or more to get that damage. And that’s only on the number 10 enemy that’s hit. Where as with Blood Spear, 650% from first hit and the next and the next. Otherwords your total damage percentage if you pass through 10 enemy for Blighted Marrow would be 632.5% average, while Blood Spear would be 650% regardless of how many it passes through. ( the odds are you never hardly go through 10)
Because Blighted is the only way you will kill elites / champions in large density in higher rifts. As previously shown in vids from PTR, the barb will pull the elite(s) on the opposite side of the necro on physical, then stun, and necro will throw those Blighted Spears that will pass through 100+ mobs to hit the elites (also dealing AD in the process).
That’s why they could do 150 with 3 supports and 1 BS necro.
That’s why for solo play Brigs is such a great ring, it allows you to stack density w/o a support doing it for you and form nice chains of packed mobs between you and that champion pack, shoot from offscreen and collect orbs ^^
Blood Spear is better in general, but in perfect mob set ups and RNG Blighted can do more damage. Blighted is better for 4mans due to being able to setup so much easier.
here’s a build you can toy around with. It’s not the best build, it’s the second best build.

Ahhm has anyone really tested blighted marrow yet?
Are the 15% a seperate Multiplier or just additive?
Because even with lower amounts of pierces i was hitting often harder than with Bloodspear.
So is it:
1st enemy: 500
2nd enemy: 515
3rd enemy: 530
Or are the 15% referring to the original 500% → 15% of 500 = 75 and thus:
1st enemy: 500
2nd enemy: 575
3rd enemy: 650
4th enemy: 725 % and so on making the break-even point 3 pierces
you also apply all 3 curses, including leech, which means that even when playing with Bloodspear ( did so in the beginning) you dont really need Grisly Tribute
it’s additive, but on it’s on multiplier.
It takes 10 passes to be equal to Blood Spear, but if you have 10 mobs it does significantly less than Blood spear because it does less damage to the 9 mobs it passed through to reach the 10th. It starts to perform better than Blood spear at around 15+ mobs. Anything less and you would have done more damage with Blood.
case a) exactly 10 mobs
case b) exactly 3 mobs
I just wanted to know if someone did a video-analysis to ensure its a) / b).
I also do assume its a) but i haven’t tested it yet. And sorry, i dont trust your word if you say you did 
It doesnt work like
500% +15%
It works like wearing a Krysbin that gives 15% to your damage per mob struck (additive)
1st mob = 15%
2nd mob = 30%
It doesnt interact with the rune damage directly.
your rune damage is set at 500%
You’re skill damage is set at 700 (maltorius spike) + gear spear bonuses
Blighted gives a separate multiplier that starts at 15% and goes up
You can basically say it’s additive, but technically it’s a multiplier.
So, basically 10 mobs to catch up to Blood spear, but you need more to get back what you lost to the previous 9 mobs that were hit before. So like i said, about 15 mobs to equal the true damage. If you pull packs of 20-30 it’s a no brainer.
It’s why double stacking pixels in front of the elites is so good. It’s why using Command skellies to proc triple krysbin on that elite behind all the packed up mobs is the sign of true skill, because you cant do that with bone armor stuns.
10 * 15 = 150 , 500 + 150 = 650.
So what you said is contradicting…
If it would be a seperate Multiplier than the Break Even Point would be 3 Mobs.
thats why i asked in the first place. Guess ill go test it on my own tomorrow
Maybe this would be easier to grasp
in your list of multipliers
Blood spear gives = 6.5
Blighted spear gives = 5.0
Blighted + 1 mob = 5 + 1.15
Blighted + 10 mobs = 5 + 2.5
Blighted + 20 mobs = 5 + 3.0
If you could snapshot blighted, then you would lock it at 6 mobs to be no different then Blood.
I hardly doubt that, sorry.
I think its either:
Blithted-Marrowdmg =
500 + (x*15)
Or the 15% refer to the Basedmg of BS which would be 15% of 500 = 75
so 500 + (x*75) with x = amount of enemies.
I dont trust your math for many reasons. See above ^
What you,ve posted there means 115 % dmgbonus with 1 piereced mob. There is no way you can twist the formula that sth like this is the result.
With 20 mobs its correct again and you took the simple 5 + (x*0.15) aproach
Corrected that for you:
No, blighted spear 500% is a separate multiplier than the bonus it receives from mobs hit. They are independent.
like i said, at about 6 mobs, the 6th mob hit by blighted will look very similar to the damage that Blood does to the first mob it hits
Sorry, i don’t trust your “math” as i think you are clueless when it comes to math. Nothing personal.
If its a seperate multiplier it woudn’t be:
It would be:
Blighted + 1 mob = 5 * 1.15
Blighted + 10 mobs = 5 * 2.5
Blighted + 20 mobs = 5 * 4.0
Leaving the Break-Even Point at the 3rd piereced mob, as stated in the original post. Gonna get some yellow equip now i guess

The damage on blighted is like this 500+15+15+15 ect. All bone spear runes are pierce except for shatter. Blood would hit first mob at 650 and ever mob after that it pierce.
I don’t know yet. I just got rid of all my crit-chance items, krysbins , eledmg, + the bracers etc, took a yellow 10 dps weapon and went to shoot some mobs with 38k sheetdmg.
With 3-4 pierced mobs im getting equal or higher hits than with Bloodspear. And with 10 mobs its around twice, which would suggest its a seperate multiplier , leaving you with basically:
500 + 75 + 75 + 75 and so on. Meaning :pierce just 2 mobs and you end up with equal dmg to Bloodspear
In addition to that, when you take poison you can take rigor mortis that procs the first stage of your krisbins , no matter where you are.
So all in all , ill stick with blighted for DPS

Well thats what i wrote in my initial post, if you would have cared to read it^^
And no its either seperate or not. Its either 3 mobs or 10. I currently think its seperate and thus 3 mobs. 6 makes no sense, in none of those 2 cases.
The table you’ve posted above is wrong, and thats ok. Happens.
Why do you keep saying it’s a separate multiplier and then saying it works like
500 + 1.15 ?
If it’s a multiplier it would be 500 × 1.15
Someone with a PhD in mathematics should know the difference between adding and multiplying

Well Precious, i think we already discovered that he didn’t really study math^^
Can anynone else do some tests?
From what ive tested now with 5 crit , no eledmg, no bracers, no areadmg, it looks like it is seperate. This would make BM the best rune without any other contender.
Outdmging Bloodspear with just 3 enemies.
