tfs 1.2 como colocar % do condition funcionar

[gusinhi 4]

fala pessoal, eu precisava de ajuda com essa spells pra colocar uma chance em % do condition Exhasted combat acertar o outro player sem que interfira no local combat

 

local combat = Combat()combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_WEAPONTYPE)combat:setParameter(COMBAT_PARAM_BLOCKARMOR, 1)combat:setParameter(COMBAT_PARAM_USECHARGES, 1)function onGetFormulaValues(player, skill, attack, factor)	local skillTotal = skill * attack	local levelTotal = player:getLevel() / 5	return -(((skillTotal * 0.01) + 1) + (levelTotal)), -(((skillTotal * 0.03) + 6) + (levelTotal))endlocal exhaust = Condition(CONDITION_EXHAUST_COMBAT)exhaust:setParameter(CONDITION_PARAM_TICKS, 1000)combat:setCondition(exhaust)local exhaustAttackGroup = Condition(CONDITION_SPELLGROUPCOOLDOWN)exhaustAttackGroup:setParameter(CONDITION_PARAM_SUBID, 1)exhaustAttackGroup:setParameter(CONDITION_PARAM_TICKS, 1000)combat:setCondition(exhaustAttackGroup)combat:setCallback(CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")function onCastSpell(creature, var)	return combat:execute(creature, var)end
