Reply 1179# ColdFlaMes17 Hehe, this is a good question.
I have the answer all along but too lazy to publish it.. since you are asked for it now....
[ The following calculation no longer applies after T4 crit mechanism revamp ]
Here it goes:
First, let
a = skill amp (the skill % in your skill description)
b = additional damage ( the number after + in your skill description)
c = base crit
C = current crit % on all your gears/plate/title/potential
D = current elemental attack % on all your gears/title/potential
M = mag attack
R = damage reduction due to defence
Lets assume that crit cap for lvl50 is 18000 and crit % is capped at 90% (which give nicer numbers at the end, rather than 89%)
We know that, the higher the target defence is, the more effective crit potential % become.
The point of this derivation is to answer this question:
what is the threshold for the defence, so that the damage of 17% crit potential is higher than 8% elemental attack?
Start with the statement:
Damage of 17% crit potential > Damage of 8% elemental attack
![]()
Therefore in order for the statement " Damage of 17% crit potential > Damage of 8% elemental attack" to be true, R (which is the dmg reduction due to defence) must be smaller than a certain value.
In otherwords, the defence of monster/boss will have to be larger than a certain threshold value in order for the statement to be true. I shall call that threshold value as R threshold.
For lv50 char,
![]()
For lv40 char,
![]()
Here, i will again use my lv50 majesty stats as an example to illustrate the calculation to get the
Threshold R value.
Again, i shall use
gravity ball lv12 as benchmark
Case 1:
a = 2.69
b = 3760
c = 11000
C = 26.5%
D = 48%
M = 8900
X = aM+b = 27701
Y = 1+D= 1.48
Z = 1+C = 1.265
![]()
You will get R threshold = 63.5%
So in order words, if the target that i am attacking has a mag defence value higher than 63.5% or 9525, it would be more effective to get 17% crit rather than 8% dark attack.
Apparently, green dragon and Kalahan are the few bosses which has over 9525 mag defence (both have 9900 mag def). The average boss defence for GDN is 7420, well below the threshold defence value.
R average for GDN = 49.47% (which is equivalent to 7420 mag def)
R average < R threshold
So, it seems that overall in GDN, i would do better with 8% dark elemental, although 17% crit would give me more DPS during the battle with the 2 final bosses.
But wait, we are forgetting 2 very important factor before making this conclusion. Yes, if you are following my post, you will realize these VERY IMPORTANT points:
i) Crit cap for lvl50 is 18000.
ii) Mercenary has a crit buff which allows you to hit crit cap, if your crit is at least 13000.
Do take note of these 2 restrictions when you are planning the build of your gear. Make sure that after calculation, your crit doesn't go over these limit or the stats will be wasted.
Case 2
Just to be fair, i will also illustrate another example whereby 17% crit is better than 8% dark elemental. This is the case where my base crit is much lower (if i use other rings instead of crit ring)
For simplicity, i will keep all the variable above unchanged, while setting
c= 6000
Therefore, R threshold = 45% (which is equivalent to 6750)
R average for GDN = 49.47% (which is equivalent to 7420 mag def)
R average > R threshold
So, in this case, if my base crit were much lower, it would be better if i get 17% crit , as compared to 8% dark elemental.
Conclusion
Don't worry if you don't understand the mambo jumbo which i have said above.
To make a decision, you only need to check and calculate the following:
i) R threshold
ii) R average
If R average < R threshold , 8% dark is better
If R average > R threshold, 17% crit is better.
Simple as that ^_^
Tips:
To make your life easier,
Average def for SDN bosses = 4418
R average for SDN = 49% if you are lvl40, 29.45% if you are lvl50
It is indeed very interesting to see that
R average is the same for GDN and SDN with lv50 and lvl40 players respectively (maybe it is purposely tuned so)
