Dragon Breath - Racial modifiers working help

[Yami]

Recently found out that Dragon Breath on my server has Racial modifiers affect the damage. ie; Hydra, AK card.

Did some tests on mob and character as well.

Tao Gunka - (8,567) NO AK card |  (10,735) 1 AK card

Player - (4556) NO hydra card | (5719) 1 hydra card

 

Searched about the issue, and found some skill.db changes as answers but nothing worked.

Tried:
 

2008,9,6,2,3,0x42,1:1:1:2:2:2:3:3:4:4,10,1,no,0,0x40000,0,weapon,0,0x0,	RK_DRAGONBREATH,Dragon Breath

to

2008,9,6,2,3,0x50,1:1:1:2:2:2:3:3:4:4,10,1,no,0,0x40000,0,weapon,0,0x0,	RK_DRAGONBREATH,Dragon Breath

also to

2008,9,6,2,3,0x70,1:1:1:2:2:2:3:3:4:4,10,1,no,0,0x40000,0,weapon,0,0x0,	RK_DRAGONBREATH,Dragon Breath

All changes did no effect to damage output. I'm in desperate need of help. I'm not very familiar with src changes regarding these kind of stuff.  Just want to remove that racial modifier in the formula/settings. Thank you!

Use expanded skill NK flags for that.

@Foob any working diff u got there..error on latest rA revision.

Add the diff manually by changing the NK flags itself. The NK flags are not updated.
