Modifying skill damage

[bodibastos]

I'd like to take the skill Crimson Rock (2800% MATK damage) and change it to 1400% ATK damage and 1400% MATK damage. I know how to lower the MATK value, but how do I add the ATK?

Thanks.

Can anyone help me?

Sorry for bumping, but it's already been 4 days

battle.c

struct Damage battle_calc_magic_attack

   #ifdef RENEWAL
 ad.damage = skill_lv * (sstatus->matk_min + sstatus->matk_max);
   #else
 ad.damage = status_get_lv(src) + sstatus->int_ + skill_lv * 10;

modify it to be something like

if( skill_num == WL_CRIMSONROCK )
{
    ad.damage = .... atk/2 + matk/2
}

depend witch atk you want but you can take a look at :

status_get_batk

status_get_watk

status_get_watk2

to get the battle-status atk of src and then alter the damage formula. (or sstatus->batk etc..) : http://rathena.sourceforge.net/doxygen/structstatus__data.html
