Como o título já diz, gostaria que alguém transformasse esse talkaction em uma spell.

Segue o script:

 

local storage = 79845 --storage para o exhaustion
local tempo = 5 --em segundos

local monsters = {
[1] = {summons = {["rat"] = {level = 10, mana = 20}, ["dragon"] = {level = 100, mana = 200} }, maxSummons = 2  },
[2] = {summons = {["rat"] = {level = 10, mana = 20}, ["dragon"] = {level = 100, mana = 200} }, maxSummons = 4  },
[5] = {summons = {["rat"] = {level = 10, mana = 20}, ["dragon"] = {level = 100, mana = 200} }, maxSummons = 4  },
[6] = {summons = {["rat"] = {level = 10, mana = 20}, ["dragon"] = {level = 100, mana = 200} }, maxSummons = 6  },
[9] = {summons = {["rat"] = {level = 10, mana = 20}, ["dragon"] = {level = 100, mana = 200} }, maxSummons = 6  },
[10] = {summons = {["rat"] = {level = 10, mana = 20}, ["dragon"] = {level = 100, mana = 200} }, maxSummons = 8  },
}

function onSay(cid, words, param, channel)
if exhaustion.check(cid, storage) then
doPlayerSendTextMessage(cid, 22, "You are exhausted.")
return true
end

    --Player Status
    local playerpos = getPlayerPosition(cid)
    param = string.lower(param)
    local loop = 0
  
    function checkSummon()
        for k, v in pairs(monsters[getPlayerVocation(cid)].summons) do
            if param == k then
                return true
            end
        end
        return false
    end
  
    if not checkSummon() then
        doPlayerSendCancel(cid, "You can't summon this monster.")
        return true
    end
  
    for k, v in pairs(monsters[getPlayerVocation(cid)].summons) do
        if (param == k) then
            if (monsters[getPlayerVocation(cid)]) and #getCreatureSummons(cid) >= monsters[getPlayerVocation(cid)].maxSummons then
                return doPlayerSendCancel(cid, "Você já tem sumons demais.")
            else
            --Summon
                if getPlayerLevel(cid) < v.level then
                    return doPlayerSendCancel(cid, "Você não possui level suficiente.")
                elseif getCreatureMana(cid) < v.mana then
                    return doPlayerSendCancel(cid, "Você não possui mana suficiente.")
                end
                    doConvinceCreature(cid, doCreateMonster(param, playerpos))
                    doPlayerAddMana(cid, -v.mana, false)
                    exhaustion.set(cid, storage, tempo)
                    doSendMagicEffect(playerpos, 2)
                return true
            end
        end
    end
    return true
end
