so.... i have a feeling a lot of ppl dont know or dont fully understand (or dont care lol) how dmg calculation and atb ticks are working

thats why i'm creating this thread to try and make a few things clearer about how it works (we will have some math here so pls bear with me - i will try to simplify it as much as possible)

before i start i want to give credits to ChouTenshi - i didnt know most of the info myself up until 2-3 months ago

this thread will be split into 2 (to prevent having 2 sticky threads - we already have quite a few of those)

i will be explaining how atk based dmg is calculated - hp/def/spd based dmg is very similar to atk (if its still unclear for some ppl i can add it later on)

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

first we will need to know a few values to be able to calculate the dmg:

these 4 values are enough to calculate how much dmg you can do before the reduction from defense/passives.

to calculate more exact dmg u would need this 5th value:

5b) in case there is a monster with a passive that reduces dmg (for example Darion/Dias) the reduction will be calculated after the dmg reduction from def.

(all taken from in game help tab)

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

first we will start by calculating pure dmg without reduction from def/passives - once we have that we can calculate the actual dmg done

i will be using the 4 values from before - if anyone is interested there will be a more detailed formula in the end of this post (where i will break each value to his sub components)

(i am not completely sure about #3/4 but this seems to be the case according to the in game help - if anyone knows otherwise pls be sure to correct me)

this is how it seems to be working (showing the calc for a crit):

for Lyn

(

for Akhamamir

okay - that wasnt so bad right?

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

after we calculated pure dmg we will now want to know the actual dmg done after reduction by defense

(as far as i know it is up to date)

(would be 1000/(0*3.5 + 1140) = 1000/1140 = 87.719%)

with 0 def : 1000/(0*3.5 +1140) = 87.719%

with 500 def : 1000/(500*3.5 +1140) = 34.602%

with 1500 def: 1000/(1500*3.5 +1140) = 15.649%

with 2500 def: 1000/(2500*3.5 +1140) = 10.111%

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

ok so we have pure dmg and dmg reduction - the last step is to multiply both and receive the actual dmg done

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

thats pretty much it

some skills behave a bit different since their multiplier depends on several stats or hp ratio which makes it harder to calculate

hope this helps a bit

if anyone have any updates, questions, corrections or clarifications be sure to post them

if anyone needs a

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

as i promised for those that can tolerate math a bit more - a more detailed version of the pure dmg fomula : (if u cant tolerate math u can stop reading here XD)

lets break it down to its components:

(base atk * (1 + atk% from runes + atk% from glory buildings + atk% from leader skills) + flat atk from runes) * skill multiplier * (1 + dmg from skillups% + base cd% + cd% from runes + cd% from glory building + cd% from leader skill)

thats it

(i ignored passives because the buff might be applied differently depending on the passive - some r according to base atk and some are according to total atk)

im just gonna leave here a quote containing a detailed explanation

if anyone have any questions about it be sure to reply and ill try to help the best i can

**Damage Calculation**

i will be explaining how atk based dmg is calculated - hp/def/spd based dmg is very similar to atk (if its still unclear for some ppl i can add it later on)

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

**Lets start:**first we will need to know a few values to be able to calculate the dmg:

**1) Total Attack**(atk) - consists of base atk and added atk from runes, leader skills, passives and atk buffs.**2) Total Critical Damage**(cd) - consists of base cd and added cd from runes, leader skills and passives.**3) Damage Multiplier**- the exact multiplier can be found in various places, i usually check summoner war wiki.**4) extra dmg from skill ups**- the +5/10/15% dmg you see as a skill up to a skill.these 4 values are enough to calculate how much dmg you can do before the reduction from defense/passives.

to calculate more exact dmg u would need this 5th value:

**5) Total Defense**(def) - consists of base def and added def from runes, leader skills, passives and def buffs.5b) in case there is a monster with a passive that reduces dmg (for example Darion/Dias) the reduction will be calculated after the dmg reduction from def.

**a few tips for calculating these values:****1) all extra stats from runes will be show in a green '+#' next to your base stat**(pretty basic stuff i assume most ppl know)**2) extra stats from leader skills and buildings are calculated by base stats**(for example 10% atk from Ancient Sword would add 10% of base atk)**3) atk buff adds 50% to your total atk (atk break reduces 50%)**

def buff adds 70% to your total def (def break reduces 70%)def buff adds 70% to your total def (def break reduces 70%)

(all taken from in game help tab)

**4) Reflect buff reduces the dmg done to 70% and returns 30% of the dmg to the enemy**

passives that work similarly have different percentages according to the description of the passivepassives that work similarly have different percentages according to the description of the passive

**other damage Reduction passives take effect AFTER Reflect in addition to reducing Actual Damage**(example: Reflect Buff + Knighthood = 59.5%:30%)**4) added stats from passives depends on the passive - sometimes the added amount is according to the base atk and sometimes its according to the total atk**-------------------------------------------------------------------------------------------------------------------------------------------------------------------

first we will start by calculating pure dmg without reduction from def/passives - once we have that we can calculate the actual dmg done

i will be using the 4 values from before - if anyone is interested there will be a more detailed formula in the end of this post (where i will break each value to his sub components)

__Pure dmg formula:__

1) critical hit:1) critical hit:

**Total Atk*****Multiplier*** (1 +**dmg from skillups**+**Total cd**)**2) non-critical hit / bomb dmg / heals / shields:****Total Atk*****Multiplier*** (1 +**dmg from skillups**)**3) crushing hit/fatal blow:**(

**Total Atk*****Multiplier*** (1 +**dmg from skillups**)) * 1.3**4) glancing hit:**(

**Total Atk*****Multiplier*** (1 +**dmg from skillups**)) * 0.7(i am not completely sure about #3/4 but this seems to be the case according to the in game help - if anyone knows otherwise pls be sure to correct me)

__5) brand + bonus dmg from skills:__this is how it seems to be working (showing the calc for a crit):

for Lyn

(

**Total Atk*****Multiplier*** (1 +**dmg from skillups**)) * (1 +**Skill_Bonus_Dmg**+**Brand**)for Akhamamir

(

**Total Atk*****Multiplier*** (1 +**dmg from skillups**)) * (1+**Brand**) * (1 +**Skill_Bonus_Dmg * number_of_debuffs**)okay - that wasnt so bad right?

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

after we calculated pure dmg we will now want to know the actual dmg done after reduction by defense

**the dmg reduction calculation is:****Def dmg reduction**= 1000 / (**Total def*** 3.5 + 1140)(as far as i know it is up to date)

**a few things to note about dmg reduction from defense:****1) defense doesnt reduce dmg from bombs at all!**

2) when using skills that ignore defense - it doesnt completely ignore defense, it simply calculates using the same formula as if defense was 02) when using skills that ignore defense - it doesnt completely ignore defense, it simply calculates using the same formula as if defense was 0

(would be 1000/(0*3.5 + 1140) = 1000/1140 = 87.719%)

**3) the ratio between dmg reduction and defense is not linear! the more defense u have the less more defense would affect the dmg reduction****for example:**with 0 def : 1000/(0*3.5 +1140) = 87.719%

with 500 def : 1000/(500*3.5 +1140) = 34.602%

with 1500 def: 1000/(1500*3.5 +1140) = 15.649%

with 2500 def: 1000/(2500*3.5 +1140) = 10.111%

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

ok so we have pure dmg and dmg reduction - the last step is to multiply both and receive the actual dmg done

__Actual dmg = Pure dmg * Def Dmg Reduction__-------------------------------------------------------------------------------------------------------------------------------------------------------------------

thats pretty much it

some skills behave a bit different since their multiplier depends on several stats or hp ratio which makes it harder to calculate
