Well first of all to synthesize a pure S Hippo you need all pure S mobs
Also I don't know what you need to know because your topic title and topic content is confusion so ill try to answer to the best of my ability

To check a monster grade just select the. In you monster inventory and the. Select "identify" it's only 100 silver.
