How to Nerf this Formula?

[Hadeszeus 15]

Need Help nerfing Tiger Cannon.

 

				case SR_TIGERCANNON:// ATK [((Caster consumed HP + SP) / 4) x Caster Base Level / 100] %					{						int hp = status_get_max_hp(src) * (10 + 2 * skill_lv) / 100,							sp = status_get_max_sp(src) * (6 + skill_lv) / 100;						if( sc && sc->data[SC_COMBOATTACK] && sc->data[SC_COMBOATTACK]->val1 == SR_FALLENEMPIRE ) // ATK [((Caster consumed HP + SP) / 2) x Caster Base Level / 100] %							skillratio += -100 + (hp+sp) / 2;						else							skillratio += -100 + (hp+sp) / 4;						RE_LVL_DMOD(100);					}

My server has 150 to 200k HP Ratio and this skill dealt massive damage.

I Need help on how to properly nerf the damage on 175 base level and 150k to 200k HP ratio. 

And what's the purpose of this RE_LVL_DMOD(100);

make a ratio or only get a portion of the HP/SP something like this

 

int hp = (status_get_max_hp(src) * 40 / 100) * (10 + 2 * skill_lv) / 100, // get only 40% of total max HP	   sp = (status_get_max_sp(src) * 40 / 100) * (6 + skill_lv) / 100; // get only 40% of total max SP 

 

And what's the purpose of this RE_LVL_DMOD(100);

its a renewal feature added for some skill where char's current level affects the over all damage formula of a skill..example of its use is when a char is low level and using a skill with lvl mod skill formula is penalized but if your level is equal to it or more than to the level requirements the char will gain bonus damage...
