I saw in one tread talking about defenses and some people were totally out. So for those who know it will be just boring reading, but for those who have no idea, i hope it will help them to find some new.
So if you wear 2 daggers (2x 80 elemental dmg for example) and you will use spike on guy who wear talia and 25 dd helm and you would hit for 1000 dmg, it will be like 850 dmg (pure ap dmg) and 150 will be elemental dmg (it depends on resistance of enemy its just cca and its that high, coz 2x elemental dmg of two weapons) so you will hit him for 850 * 0,5 (50% down from talia) * 0,75 (25% down from dd helm) + 150 dmg (elemental dmg as i said once it depends on resists) = 469 dmg (you hit him).
By the way if you would hit 1000 dmg without his passive skill on 75 lvl that reduce 15% all dmg it would be INCLUDE elemental dmg that means it would be 469 * 0,85 (15% reduction of 75 lvl passive skill) = 399 dmg in total.
For those who are that smart and say biggest % goes first, i would like to say you were really dumped in math at school coz its multiply and really doesnt matter if go 850*0,5*0,75 or 850*0,75*0,5 its still same result. You can try on calculator, may be you will find something new for you. )
We can continue with math as well. You will never reach 0, because item what gives 100 defense doesnt exist at all and if you would were like 5 of 50 dd which is (when someone adds this and most like to add defenses together it would be 250 dagger defense WOW amazing), but in fact its 0,5*0,5*0,5*0,5*0,5 = 0,03125 reduction and still when you would wear this and someone would hit you for 1000 (31,25 dmg after reduction) it will still hit you for more 150 of elemental dmg so in total he would hit you for 150+31,25 = 181,25 dmg so you will never reach total 0. So myth about over 70 defenses doesnt works is out as well. It will reduce, but it will be small numbers.
This works only on Rogue, because he going with pure dmg mostly (except elemental dmg of weapons)
Now i will explain how does it works with warriors and priests. (same calculation actually)
If you hit for 1000 with warrior (by for example axe with 165 elemental dmg, well known weapon ) ) it goes with hell blade skill and thats 300% of dmg + 350 additional (1/3 reduction in PVP, added because of argue). So it will goes for 500 (pure ap dmg) + 350 skill dmg (1/3 reduction in PVP, added because of argue) + 150 elemental dmg (1000 dmg in total) and enemy will wear chitin shield 50 axe defense and talia 50 axe defense it will calculate only with that 300% (pure ap part) so it will be 500 * 0,5 (50% down by chitin shield) * 0,5 (50% down by talia) + 350 of skill dmg (1/3 reduction in PVP, added because of argue) + 150 elemental dmg (as i said before it depands on resistance of enemy) = 625 dmg you hit him (392 dmg with 1/3 PVP reduction of 350 skill additional dmg, added because of argue)
Same as dagger defense example, when you hit enemy by 1000 dmg without 70/75 passive skill reduction, which will reduce ALL dmg by 10/15% it will be 625 dmg * 0,85 (15% reduction of 75 lvl passive skill) = 531 dmg in total (333 dmg with 1/3 PVP reduction of 350 skill additional dmg, added because of argue)
Just in case i would like to say again that warrior what would hit you for 1000 dmg without any reduction (even 75 lvl master skill) would HIT enemy that HAVE (like most add together) 100 axe defens and 75 lvl skill reduction for 531 dmg!!!!! (333 dmg with 1/3 PVP reduction of 350 skill additional dmg, added because of argue)
For those who want to compare, if there would be 2 items that could do (like most add together) 100 defense like on warrior example (so one item 50 dagger defense (talia exist) and second 50 dagger defense (no other item have this, its just to compare with warrior) ) and that guy would hit for 1000 dmg without any reduction as in warrior example it will be same 850 (pure ap) + 150 (elemental dmg) so [(850 * 0,5(talia) * 0,5(example item for compare))+150(elemental dmg)] * 0,85 (75 master skill reduction) = 308 dmg
So if you will compare warrior and rogue with same conditions of 1000 dmg without any reduction and you will reduce them it will be 531 dmg (333 dmg with 1/3 PVP reduction of 350 skill additional dmg, added because of argue) by warrior and 308 dmg by rogue!!!
It doesnt really work on only on rogues. Ya if you are good in math and you will know that rogue have NO adds on dmg and it reduce almost all dmg (except elemental dmg) it will be good numbers!!! But warriors and priests use additional dmg in their skills, so defense works only on XXX% part (like on hell blade 300% only this part) so rest (like 350 additional dmg of hell blade and elemental dmg) doesnt work on it. Thats why it works so hard on rogues.
Every XXX added dmg of skill (except elemtal ones, like fire arrow etc.) are NOT resistable and only thing that it reduce is 70/75 lvl passive skill in mastery skills 10% and 15% reduction. If you dont trust me you can just try simple example. Let hit yourself by warrior skill Blooding and it will hit you for 1000 dmg for 20 sec, so in fact it will hit you for 100 dmg every 2 seconds, but if you have 15% passive skill reduction (75 lvl) it will hit you for 85 dmg constantly (no matter any defense, ac or resistance).
Guys, i would like to say all this i have found out on JP KO, because weapons there using elemental dmg much more then here on US KO and conditions are same. People which wear really high defenses were fucked anyway when you wear dual 250 elemental dmg daggers and many more other things. It was kind of research for me.
One more and most important thing i wanna say in the end of this. Everything here what i wrote is just math guesses and if you will calculate by this way you will find out that it works, but noone ever who made KO didnt say me "yea this is the code". So its just guess...
I hope you enjoy it.....Now you can flame me.... )
