After the efforts of the Diablos the walls of Primus have been strengthened across Primus. As such until the end of the year (although it may be extended) all Demonkind, Angelkind, and similar other worldly beings count as being one level lower for the purposes of being banished from Primus.
This does not reduce an undeads dismiss level.

The applies across all of Primus.
