AOE that only damages creatures

[freaked1]

Hello, if I use "exevo gran mas vis" in this example, is it possible to make it only do damage to creatures and not players?
I only want certain spells to be like that.
EDIT: TFS 1.1

Unchanged rage of the skies.lua:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_BIGCLOUDS)

local area = createCombatArea(AREA_CROSS6X6)
setCombatArea(combat, area)

function onGetFormulaValues(cid, level, maglevel)
    min = -((level / 5) + (maglevel * 4) + 75)
    max = -((level / 5) + (maglevel * 10) + 150)
    return min, max
end

setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

function onCastSpell(cid, var)
    return doCombat(cid, combat, var)
end

local combat = Combat()
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_BIGCLOUDS)
combat:setArea(createCombatArea(AREA_CROSS6X6))

function onTargetCreature(player, target)
    local level = player:getLevel()
    local maglevel = player:getMagicLevel()
    local min = (level / 5) + (maglevel * 4) + 75
    local max = (level / 5) + (maglevel * 10) + 150

    if target:isMonster() then
        doTargetCombatHealth(0, target, COMBAT_ENERGYDAMAGE, -min, -max, CONST_ME_NONE)
    end

    return true
end

combat:setCallback(CALLBACK_PARAM_TARGETCREATURE, "onTargetCreature")

function onCastSpell(creature, variant)
    return combat:execute(creature, variant)
end

Thank you so much! It works on creatures without an error, have yet to test it with players.
Only had to change "(maglevel * 10) + 150" to "(magLevel * 10) + 150".
