Hi, I'm Esna, i write this report cause after some test i witnessed that the formula i found on Kro is maybe different than the formula present actually on the server.
The damage formula for Nova Explosion in Kro is ※ 추가 데미지 = MaxHP / (6 - SkillLV) + (MaxSP * (2 * SkillLV)) .
During all those tests i will make, my AB and my Star Emperor got no gears on.
After the comment by a fellow player, i will add 2 more test to this report.
The first test is the test where all my stat are at 1:
As you can see, my max HP is actually 24905 and my max SP is 1463 (before the cast of Nova Explosion Lv 5), so if I apply the KRo formula my total damage have to be :
24 905 / (6-5) +(1463*(2*5))= 24 905 +14 630 =39 535 damage, but as you can see on the screenshot above i dealt only 21 271 damage.
The second test is the test where i put my hp at 1 and my sp at just the good amount to cast the spell, i still have all my stats points at 1:
As you can see during the second test, i got 2/(24 905) HP and 80/(1463) SP.
If we follow the KRo formula, here come the damage that have to appear: 2/(6-5) + (80*(5*2))= 802 damage.
But here in the screenshot we can see that i dealt 1905 damage which is not the same as the formula from KRo.
The last test is the test where i got all my stats ponit put and with max hp and sp.
My Ab got no gears so there are no redux damage based on gears.
As you can see on the screenshot above I dealt 37 615 damage with nova explosion level 5.
Moreover, you can see in the file that Nova explosion is a fixed neutral damage that can't be reduced by any effect.
If i use the Kro formula damage: MaxHP / (6 - SkillLV) + (MaxSP * (2 * SkillLV)) , my damage is supposed to be 43 362 / (6-5) + (2410*(2*5)) = 43 362 + 24 100=67 462.
Even if we take in the formula the reduction induced by the the silk pvp melee damage the damage is not supposed to be 33k, half the correct damage on Kro.
