Hello !

I was wondering, i saw a few guys using Seraph's instead of hl and i honnestly didn't think about it before. Would it be superior in terms of raw dmg with a weapon that already has 50%dmg to undead such as eth tm/archon staff ?

My build is eth insight archon (257ed/5crit) and phenix.

Lmk if u have any clue

Peace !

Lvl 6 crit = 46% crit
Levitation mastery = 36% crit?

Gores = 15% ds
Highlord's = 37% ds if max level.

The 2 critic sources rolls individual. And they roll individual to deadly strike as well.

CritTot = 1-(1-CS1)*(1-CS2)
CritTot = 1-(1-0,46)*(1-0,36) = 0,6544 * 100 = 65,44% crit

Deadly strike only if crit fails:
DS = (1-CritTot)*DS
DS = (1-0,6544) *0,52 = 0,1797 * 100 = 17,97% deadly strike

ChanceToDouble:
CtD = CritTot + DS
CtD = 65,44+17,97 = 83,41%

Thats a good start.
Put in your damage numbers. Calc it with and without HL. Remember the dmg to undead/demons. Best done in excel.

i used seraph and never go back

49 dtu and 49 dtm just too nice and 2+ all skill which is another 1% there for critical strike

(0,75*WeponDamage + Skilldamage) * (1+((Stabonus%+Aurabonus%+OffhandED%+MasteryEd%)/100)) * (1+(EchoingSkillDamage%+Synergi%)/(2*NumberOfHits)

Highlords wins when you have more than 700% offhand/statbonus/aurambonus ed.
(Phoenix 400, Might 320?, strenght 156+, pride 280?, demon fana maby 80?, consume is some ed% as well, sling can be ed% jewels in helm can be ed%), Your way beyond 700% ED and highlord should win.

Probabilities don't work that way.

If you have two independent events you can't sum them.

If you have a first event with a 60% chance (crit) and a second with 40% chance (deadly strike) and they roll one after another, you don't have a 100% probability to double damage.

I already did that, which is why crit landed at 65% and deadly strike landed at 18%.
Then once that is done they can be added.

DoubleChance = 1-(1-CS1)(1-CS2)(1-DS)
Double chance = 1-(0,54*0,64*0,48)
Double chance = 1-0,1659 = 0,8341, aka the same number as adding the already "nerfed" numbers.

What i did not do was to scale the critic% of insight based on +all skill levels.

We can try to set up a full multiplication, for excel:

Critical strike%: =min(5 + (75 * ( (110*slvl) / (slvl+6) ) / 100) ; 80)

DoubleDamageChance: = 1-(1-CS1)(1-CS2)(1-DS)
(Multiply it by 100%, this is a direct factor).

Damage for echoing strike, % to undead/demons should be as located below:
Vs normal: (0,75*WeponDamage + Skilldamage) * (1+((Stabonus%+Aurabonus%+OffhandED%+MasteryEd%)/100)) * (1+(SkillDamage%+Synergi%)/(2*NumberOfHits)
Vs demons: (0,75*WeponDamage + Skilldamage) * (1+((Stabonus%+Aurabonus%+OffhandED%+MasteryEd%+DamageToDemon%)/100)) * (1+(SkillDamage%+Synergi%)/(2*NumberOfHits)
Vs undead: (0,75*WeponDamage + Skilldamage) * (1+((Stabonus%+Aurabonus%+OffhandED%+MasteryEd%+DamageToUndead%)/100)) * (1+(SkillDamage%+Synergi%)/(2*NumberOfHits)

Perf ETH archon Insight 15% base, average damage:
(474+555)/2 =

But the issue is, SkillDamage in this formula. That is before synergies? I would assume such, but is it also before skilldamage%? Because those numbers differ a lot! xD

Because, when i backcalced from d2planner i found that:
Skilldamage% = ESlvl*5+25
Min damage = ROUNDDOWN((5+(3*EsLvl))*(1+(SkillDamage%/100));0)
Max damage = ROUNDDOWN((7+(5*EsLvl))*(1+(SkillDamage%/100));0)
Numbers of echoes = MirroringBaseLvl/5

So, i dont know yet if SkillDamage is before or after the Skill% is added in the formulas above.
But i will try to find out. Building excel sheet atm xD

I would assume as much. And then Formula for SkillDamage would be: 5+3*Slvl and 7+3*Slvl

We can try with both. I just feel that i heard in the youtube video that skilldamage% is added twice, which means its already included before its applied in the last step of formula as well...

Lol Gel I didn’t know it would take so much calc

Interested in the results if you guys find a way to calc it, this is way above my math/excel skills haha

You actually dont need to do the damage calc.
They are both increasement factors... Which is why 700% offhand ED is the breakpoint where Highlord starts winning.
Below 700% offhand ED Seraph's wins.

But i will do full calc for my own interest and to verify that

no. 50 ed is nothing compared to what you can get out of your amu slut

if you don't want the DS at least use an fcr amu which amongst other things could let you use loh for 350 ed
