| Knights of the Round | Round Island (take a Sea Chocobo out to the uncharted isle in the upper right corner of the map.) | Definitely the coolest and most powerful summon spell you can get. Can do upwards of 100,000 points of damage. |
| Master Summon | Cosmo Canyon | If you can manage to get all the summon materias to Master level, go to the Huge Materia in Cosmo Canyon to get this one, which allows you to summon anybody you want. Like the other Master materias, it does not gain AP and doesn't reproduce. |
