How can I change Steel Crow passive bonus?

[kyenard]

Hunter's Steel Crow is getting awkward. All I could find about the skill while checking the Battle, Status, Skills.c files was the following code line:

		case HT_BLITZBEAT:
		case SN_FALCONASSAULT:
			{
				uint16 skill;

				//Blitz-beat Damage
				if(!sd || !(skill = pc_checkskill(sd,HT_STEELCROW)))
					skill = 0;
				md.damage = (sstatus->dex / 10 + sstatus->int_ / 2 + skill * 3 + 40) * 2;
				if(mflag > 1) //Autocasted Blitz
					nk |= NK_SPLASHSPLIT;
				if (skill_id == SN_FALCONASSAULT) {
					//Div fix of Blitzbeat
					DAMAGE_DIV_FIX2(md.damage, skill_get_num(HT_BLITZBEAT, 5));
					//Falcon Assault Modifier
					md.damage = md.damage * (150 + 70 * skill_lv) / 100;

What I understand is, this code only says whats is going to happen IF Steel Crow is not being considered on the calculations. Where exactly I can change to affect only the Steel Crow passive?

Thanks in advance to anybody reading this.

md.damage = (sstatus->dex / 10 + sstatus->int_ / 2 + skill * 3 + 40) * 2;

skill is equal to Steel Crow level.
