Cria um arquivo .lua em data/creaturescripts/scripts e coloca isso:

function onLogin(cid)

local storage = getPlayerStorageValue(cid, 2014042021)

if storage ~= -1 then
	doPlayerSetVocation(cid, storage)
end

return true
end

Depois é só colocar a tag no creaturescripts.xml (me avisa se vc n souber fazer)
