The armor set known as "Class Up Armor (Liber Paladin)" from Bandai is compatible with their line of plastic models, specifically the "30MF (30 Minutes Fantasy)" series. By replacing the armor components, this set allows for an upgrade to a higher-tier job, namely the Liber Paladin.

To achieve this advancement, one can combine this armor with the separately available Liber Knight. The Paladin role boasts superior sword skills compared to a standard knight and offers enhanced physical defense capabilities. Notably, the facial design and coloring of this Paladin set differ from that of the Rozan Empire's Paladin, which is sold as a separate item.
