Focus Effect - > Max Level effectiveness reduction question

[bad_captain]

Is there a way to make a focus effect max level an actual max level and not begin effectiveness reduction?

                case SE_LimitMaxLevel:{
			int lvldiff = (spell.classes[(GetClass()%16) - 1]) - focus_spell.base[i];

			if(lvldiff > 0){ //every level over cap reduces the effect by spell.base2[i] percent
				lvlModifier -= spell.base2[i]*lvldiff;
				if(lvlModifier < 1)
					return 0;
			}
			break;
		}

This code checks to see if the spell level is > maxlevel for the focus effect, then reduces the effectiveness by the lvldiff, which should be specified in the spell table.

The focus effect in question (Pet Focus) has 0 for base2[i], which should be a percentage to reduce per level. With a 0 for per lvl reduction, spell.base2[i]*lvldiff; will = 0, which means lvl modifier will stay at 100. Unless I'm wrong, this means the focus effect will stay at 100% effectiveness for every level, no matter the maxlevel.

Would there be any issue with changing

if(lvlModifier < 1)
     return 0;

to

if((lvlModifier < 1) || (spell.base2[i] == 0))
	return 0;

This would make any focus effect which has a per level over maxlevel reduction percentage of 0 stop working completely if the spell level is above the focus effects maxlevel.

If I get this worked out, then I will have finished a relatively scalable pet focus solution, but I want to make sure it will not adversely affect any other spells or code, as I'm not that familiar with spells.
