Trivia

 * There are 5 notches in the Godtuner section of the Inventory. Each notch corresponds to each pantheon in Godhome. Each notch will change appearance according to the completion status of the corresponding pantheon (which includes the bindings used).
 * The Godtuner is referred to as "GODFINDER" in the game's files.
 * The circle in the very centre of the Godtuner, when viewed in the inventory, will glow when there has been a new boss added into the Hall of Gods. When the new boss has/bosses have been checked in the hall, the light will turn off.
