Make ultimate explosion rune 5 sec exhaust at pz

[Koxose]

Is it possible to make ultimate explosion rune 5 seconds of exhaust at pz mode?
Im having thunderstorm rune hitting 50% lesser when at pz. And this is the script for it:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_ENERGYHIT)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGYBALL)

function onGetFormulaValues(cid, level, maglevel)
    local min = level * 0.2 + maglevel * 1 + 6
    local max = level * 0.2 + maglevel * 2.6 + 16
    return -min, -max
end

setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")
local area = createCombatArea(AREA_CIRCLE3X3)
setCombatArea(combat, area)

local lowerCombat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_ENERGYHIT)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGYBALL)

function onGetFormulaValues(cid, level, maglevel)
    local min = level * 0.2 + maglevel * 1 + 6
    local max = level * 0.2 + maglevel * 2.6 + 16
    return -(min*0.5), -(max*0.5)
end

setCombatCallback(lowerCombat, CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")
local area = createCombatArea(AREA_CIRCLE3X3)
setCombatArea(lowerCombat, area)

function onCastSpell(cid, var)
    if(isPlayerPzLocked(cid)) then
        return doCombat(cid, lowerCombat, var)
    end

    return doCombat(cid, combat, var)
end

So im sure it's also possible to make a 5 sec exhaust on pz? Only on pz.
