Rune: 20%ES or 2% Max Mana?

I'm doing Archmage+CI+Eldritch Battery+MoM, around 5600 ES, 4200 Mana. Which 1209 ES from my gear turns into Mana.
I need help deciding/visualizing which rune would be better to use on my gear to maxout Mana/ES as much as possible.

Either 20% ES or 2% Max Mana.

ES Values
Helmet: 244
Body: 624
Boots: 180
Focus: 94
Gloves: 67

Hi, I just started playing this game i have 300+ hours i hope this can help you!.

Firs of all never ever use sould core for 2% mana if your running Eldrich battery while you are low level or low gear

Second if you are using Atziri's Disdain Golden Circlet than make sure you have also +Life on your Body Armor

you main stats will be
+to energi shield
%increase to energy shield
To mana
Int
Cast Speed
Elemental/spell damage (cold, Fire, Lightning)
To maximum life if your using (Atziri's Disdain Golden Circlet)
the rest of the stats should be for your Resistance and stun or freeze threshold
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

this includes The everlasting Gaze Azura Amulet and in this calculation lets say that the Amulet has an effect of 30% of Maximum mana. keep in mind as long is you have Eldrich battery even without the Amulet you should always follow this math!.

The Base mana will be 1000
And Base Energy shield 800

And we have (sould core 2%mana)
Iron Rune 20% increas to energy shield and Armor AND EVASION.......



# for the sould core 2%mana

1000 x (1+0,02) = 1020 mana after 1 sould core

Without the Amulet you gain 0 increase to energy shield

with amulet 30% effect

30% of 1020= 1020 x 0,30= 306 + 800= 1106 Total energy shield......

With Eldritch Battery

1020+1106=2126 Total MANA

Your total mana = 2126
Your total Energy shield = 1106


--------------------------------------------------------------------------------------------------------------------------------

# For the Iron Rune

The Base mana will be 1000
And Base Energy shield 800

+20% to ARMOR,EVASION and ENERGYSHIELD

Total mana after 1 Iron rune = 1000

20% Iron Rune = (800 x 0,20) = 160 + 800 = 960

Energy shield With Everlasting Gaze 30% effect

30% off 1000 = 1000 x 0,30 = 300 To the energy shield From the Amulet

Total Energy Shield = (160 + 800)= 960 + 300 = 1260

With Eldritch Battery

Base Mana 1000 + 1260 = 2260 Total effective mana


Your total mana= 2260
Your Total Energy Shield= 1260

------------------------------------------------------------------------------------------------------------------------------------------------------

Final resort....

Soul core 2% mana=
Your total mana = 2126
Your total Energy shield = 1106
----------------------------------------------------------------

Iron Rune 20% increase to Armor, Evasion and energy shield

Your total mana = 2260
Your Total Energy Shield = 1260

------------------------------------------------------------------------------------------


Keep in mind that if your base energy shield stay at 800 with no modifiers than the soul core will surpass the iron rune after 6k+ mana

If you keep increasing the Energy Shield with modifiers than the Iron rune will have higher value for your effective mana

same goes with the Soul Core if you have Modifiers that increases your mana pool like "To mana" and "Intellect" than it will surpass the Iron rune


So in order to know witch one has higher value you simply have to add your mana modifiers and energy modifiers to the base and than do the calculation

they both are very close in value Though Iron rune does offer more survivability

If you are increasing your Energy modifiers and Mana Modifiers Equally than the Iron rune will stay the better choice do to the 20% increase compared to the 2% increase

however if your base mane is 5000 and your energy shield stays at 800 than the soul core will give approximately 10-11 more base mana

if you are Using a Shield like "Mahuxotl's Machination Omen crest shield" with modifiers like 500% increased armor and energy shield and 600% increased effect of socketed soul cores
and you have 2 soul cores

than you get 14% for each soul core socketed

we have a modifier with 600% and base mane is 100%

we add the two together will give us 700% and if we convert that to decimal faction 700/100=7

than we multiply that with with the 2% mana from soul core

7x2=14% increase per soul core and multi play that by X amount of soul core you have socketed into the shield in this case 2

14 x 2 = 28% increase to total mana from shield in this case the soul core will give you more to total mana

however if you are using soul core on all your gear that i will result in less total mana than having soul core on modifiers like 600% increase to the soul core.

so only use Soul core +2% mana on Gear with modifiers like 600%+

Else you should Use Iron Rune on all your gear piece with the setup of Gaze and Eldritch Battery


so in order to calculate everything you have to also look in to whatever modifiers you have passive talents and so on.

but keep in mind that if you are using Eldritch battery than you are converting all energy shield to mana witch result in you have 0 energy shield so any increase to energy shield from passive nodes will not give any mana to EB Since you are Multiplying it By 0. and if you are Gaining Life As EXTRA energy shield or Gain X% of mana as EXTRA energy shield than you are creating a new energy pool (B). Though any Passive Skill Nodes that increases your Mana will effect your B energy pool with items like Everlasting Gaze

safe bet just use IRON RUNE!

I'm doing Archmage+CI+Eldritch Battery+MoM, around 5600 ES, 4200 Mana. Which 1209 ES from my gear turns into Mana.
I need help deciding/visualizing which rune would be better to use on my gear to maxout Mana/ES as much as possible.

Either 20% ES or 2% Max Mana.

ES Values
Helmet: 244
Body: 624
Boots: 180
Focus: 94
Gloves: 67



in this case we add all the ES value from gear

and assuming that were are only adding 1 Iron rune

Current Gear ES= 1209
than we multiply that with the 20% modifier
1209x0,2=241.8

so your getting 241 ES added to the total ES of 5600

5600+241.8=5841.8

Now we converting the ES TO mana with Eldritch battery

1209+241.8=1450.8 will be converted by EB

your new mana pool will be 4200+241.8=4441.8

-------------------------------------------------------------------

now for the soul core 2% mana

current mana 4200

and we are increasing it by 2%

4200x0,02=84 mana increased

your total mana after increase will be 4200+84=4284

Another Example..

IF you are adding Iron rune to Helmet that has 244 Base Energy Shield than you are multiplying 244x0.2=48

your helmet now has 244+48=292,8 witch than converts to mana by EB
and then you do the same calculation to each piece individually and than add them together to get a total result.

Same if you are to calculate ES increase that you get from Everlasting Gaze

the X% gain from EG is multiplied by the amount of energy shield that you got from applying the Iron rune to the helmet.

x% Multiplied by 48= Z that gets added to the B energy pool
---------------------------------------------------------------------


-------------------------------------------------------------------this is for my own setup!.

Iron runes on All items

Head + 16,4 mana

Chest 182,8 mana

Boots 21 mana

Gloves 6,4

Total of 226,6


Without any sockets


Head 65,6 ES x

Chest 274,2

Boots 85,6 ES

Gloves 32



Total mana 3958 - Iron rune= 3 731,4

if we add 5 Soul core 2% x 5 10% more mana

were are getting 373,14 mana added to the pool

----------------------------------------------------------------------------

if we are to use 2 iron runes = 40% to the chest piece than we are adding 182,8

now we are adding 182,8 to the base mana= 3913,8

and now we add 3 soul core = 6%

0,06x3913= 234,78 mana added

now if we would calculate the total increase of adding 2 iron runes to the chest and adding 3 soul core to the rest of the gear

we are getting an increase to the mana by= 417,628
