However, advancing from the Overlord tier to the Saint tier wasn't an easy task. Otherwise, there would have been an abundance of Saint-tier monsters by then. In order to reach the Saint tier, there were a few more requirements other than level requirement that an Overlord-tier monster had to meet.
