Help with paralyze spell in area

[bizao030188]

Hey there,
I am trying to implement a spell that paralyzes monsters in a certain range.
This is what I have so far:

local condition = Condition(CONDITION_ATTRIBUTES)
condition:setParameter(CONDITION_PARAM_TICKS, 4000)
condition:setParameter(CONDITION_PARAM_SPEED, 50)

local combat = Combat()
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_STUN)
combat:setArea(createCombatArea(AREA_CIRCLE6X6))
combat:setCondition(condition)

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

The effect is showing but nothing happens to monsters around. What is the best away of doing that?

Thanks in advance.

local combat = Combat()
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_STUN)
combat:setArea(createCombatArea(AREA_CIRCLE6X6))

local condition = Condition(CONDITION_PARALYZE)
condition:setParameter(CONDITION_PARAM_TICKS, 4000)
condition:setParameter(CONDITION_PARAM_SPEED, -50)
combat:setCondition(condition)

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

Source of CONDITION_PARAM_SPEED

bool ConditionSpeed::setParam(ConditionParam_t param, int32_t value)
{
    Condition::setParam(param, value);
    if (param != CONDITION_PARAM_SPEED) {
        return false;
    }

    speedDelta = value;

    if (value > 0) {
        conditionType = CONDITION_HASTE;
    } else {
        conditionType = CONDITION_PARALYZE;
    }
    return true;
}

or just modify paralyze rune script
