The Gavel is a powerful entity that the players will encounter after defeating Mr.58 on Floor 50 of the Otherworld Tower dungeon. The Gavel is an entity that is supposedly the other identical entities of The Pommel. Just like The Pommel, it also prevents the players from accessing the Otherworld dimension.
Not to be confused with The Pommel, The Gavel appears in the Otherworld Tower for the rest of the time the players had cleansed the dungeon in time. The Gavel is the entity that will reward the player different items that can be obtained in the Frontier, usually items that are powerful.
In its appearance, The Gavel shares nearly identical resemblances to that of The Pommel's Helmet (and The Pommel). These eyes may have been arranged to be organized in a circular manner, in a way that it is indirectly referencing the Frontier's world. Besides its head is two shoulder-pads that sit beside The Gavel's head, being visualized as black and white respectively. This is meant to reference the Otherworld.
