[Banishment to Another Plane], Fourth Ring Protection System.
Its effect is to temporarily exile a creature within the line of sight to another plane (Charisma Immunity).
After the duration ends, the target will be teleported back to the original location.
Undoubtedly, this is a highly practical spell.
Especially in group battles where there are many enemies and an elite individual is present.
Imagine this scenario: a well-equipped four-person adventurer team, unexpectedly encountering a troublesome demon capable of summoning numerous "minion-type" underlings while exploring the Underground City.
Under normal circumstances, the team needs to handle the surrounding attacks from a horde of minions while guarding against sneak attacks from the elite monster, which is very troublesome.
But if there is a spellcaster in the team who has mastered [Banishment to Another Plane], they can directly banish the elite monster from the field.
