Damage increase % cap

Hello, I am pretty new to the community and I have had some questions on how to increase the Damage increase cap. I have searched the forums and found a few threads but most of them did not explain how to apply the changes well. I then decided I would mess around with it but I had no luck.

BaseWeapon.cs

Code (text):

* The following damage bonuses multiply damage by a factor.
* Capped at x3 (300%).
*/
//double factor = 1.0;
int percentageBonus = 0;

I have tried editing this but it just increased the standard amount of damage.
I am looking to have a cap of 500%. So if I were to have a cumulative bonus of lets say 400% damage increase and a dagger that did 10-11 damage it should display 40-44 not including strenth bonus. Could anyone please show me the exact line to edit so i can achieve this cap? Any help will be appriciated.

*Edit

I seem to have figured it out. If anyone is interested in changing the AOS attribute weapon damge cap it can be found in BaseWeapon.cs

Code (text):

#region Modifiers
            /*
            * The following are damage modifiers whose effect shows on the status bar.
            * Capped at 100% total.
            */
            int damageBonus = AosAttributes.GetValue( attacker, AosAttribute.WeaponDamage );

            // Horrific Beast transformation gives a +25% bonus to damage.
            if( TransformationSpellHelper.UnderTransformation( attacker, typeof( HorrificBeastSpell ) ) )
                damageBonus += 25;

            // Divine Fury gives a +10% bonus to damage.
            if ( Spells.Chivalry.DivineFurySpell.UnderEffect( attacker ) )
                damageBonus += 10;

            int defenseMasteryMalus = 0;

            // Defense Mastery gives a -50%/-80% malus to damage.
            if ( Server.Items.DefenseMastery.GetMalus( attacker, ref defenseMasteryMalus ) )
                damageBonus -= defenseMasteryMalus;

            int discordanceEffect = 0;

            // Discordance gives a -2%/-48% malus to damage.
            if ( SkillHandlers.Discordance.GetEffect( attacker, ref discordanceEffect ) )
                damageBonus -= discordanceEffect * 2;

            if ( damageBonus > 100 )     [B]//Change this to what you like//[/B]
                damageBonus = 100;       [B]//Change this to what you like//[/B]
            #endregion

which part do you change though?? thepart all the way to the bottom? and if so, do the numbers have to be the same?

if ( damageBonus > 100 ) //Change this to what you like// damageBonus = 100; //Change this to what you like//

Yes they should be the same.
