totalReduction[SCHOOL] = 1 - ((mobSpellCritChance * (1 + mobSpellCritBonus) * mobSpellCritDamageMod) + (1 - mobSpellCritChance - mobSpellMissChance)) * (1 - schoolReduction[SCHOOL]) * spellTakenMod

Armor Reduction
levelModifier = attackerLevel if ( levelModifier > 59 ) then levelModifier = levelModifier + (4.5 * (levelModifier - 59)) end armorReductionTemp = armor / ((85 * levelModifier) + 400) armorReduction = armorReductionTemp / (armorReductionTemp + 1) if armorReduction > 0.75 then armorReduction = 0.75 end if armorReduction < 0 then armorReduction = 0 end

Defense Effect
defenseEffect = (defense - attackerLevel * 5) * 0.04 * 0.01
