There are some Psynergy spells that can only be used by enemy Adepts, such as Agatio. The player cannot use these without a hacking device and can only see them when battling the appropriate enemies. Enemy Psynergy differs from Monster Skills in that a Psynergy seal will not prevent enemies from using the latter. It is possible to tell the difference in-game because the battle text says that enemies "use" or "unleash" Monster Skills and "cast" Psynergy.
