Mana Rune por level

Ola gostaria de ajuda para modificar esse script de mana rune.

Gostaria que o random muda-se apartir do level do player e da vocação também exemplo:

level 50 mage cura de 100 a 150

level 50 pally cura de 70 a 80

level 50 kina cura de 40 a 50

level 100 mage cura de 200 a 250

level 100 pally cura de 100 a 150

level 100 kina cura de 50 a 120

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_TARGETCASTERORTOPMOST, 1)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, 0)
function onCastSpell(cid, var)
local pally = math.random(300,450) -- minimo mana, maximo mana
local mage = math.random(550,600) -- minimo mana, maximo mana
local kina = math.random(250,300) -- minimo mana, maximo mana
local vocation = getPlayerVocation(cid)
if vocation == 3 or vocation == 7 then
doCreatureAddMana(cid, pally)
doSendAnimatedText(getPlayerPosition(cid), "pally", TEXTCOLOR_BLUE)
elseif vocation == 4 or vocation == 8 then
doCreatureAddMana(cid, kina)
doSendAnimatedText(getPlayerPosition(cid), "kina", TEXTCOLOR_BLUE)
elseif vocation == 1 or vocation == 2 or vocation == 5 or vocation == 6 then
doCreatureAddMana(cid, mage)
doSendAnimatedText(getPlayerPosition(cid), "mage", TEXTCOLOR_BLUE)
return doCombat(cid, combat, var)
end
end
