spell condition

alguem me ajudar a fazer essa condition a bater o mesmo level da pessoa que usar, agradeço desde ja pq n tenho ideia de como fazer

local condition = Condition(CONDITION_FIRE)
condition:setParameterCONDITION_PARAM_DELAYED, 1)
condition:addDamage(5, 3000, -25)
condition:addDamage(1, 5000, -666)

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_FIREDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_FIREAREA)
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_FIRE)
combat:setFormula(COMBAT_FORMULA_LEVELMAGIC, -1.3, -30, -1.7, 0)
combat:setCondition(condition)

function onCastSpell(creature, var, isHotkey)
    return combat:execute(creature, var)
end
