Roguelocke
Roguelocke mode is a game mode that can be accessed from the main menu after attempting Guildmaster Trail for the first time.
Gameplay

The objective of Roguelocke mode is to successfully complete a dungeon while starting the run with no items and only one Pokémon. While the Player must begin with one Pokemon, they may still recruit new members over the course of the dungeon, and the run may still be completed by one of those members even if the starter has fainted.
Any Pokémon that the Player has obtained in the main story or in a prior Roguelocke run may be chosen as a starter. Additionally, if an already-evolved Pokémon has been recruited, its pre-evolutions will be available as well. The starter Pokémon is customizable, with all abilities and alternate forms being selectable even if they were not previously unlocked by the Player in the main story. However, the starter's moveset cannot be changed, and will always contain the 4 most recently learned moves at that dungeon's starting level.
A Roguelocke may be saved and resumed at any time, but after a defeat the Player must begin the dungeon over from scratch, with no option to be rescued.
Transfer
If a dungeon is successfully completed, the Player is given the option to transfer any items or recruited Pokémon they obtained to their story save. While all Roguelocke dungeons allow items to be transferred, only some allow Pokémon to be.
When transferring items, everything currently in the Player's bag or held by a party member will be moved to their story save's storage unit. In the case of some dungeons, this can be used to get extra copies of an item that normally only appears once in the game's story.
When transferring Pokémon, the starter as well as any Pokémon recruited over the course of the dungeon will be added to their story save's assembly. This includes not only the active party, but also any members who fainted or were sent back to the Roguelocke team's assembly.
If beginning the dungeon as a shiny Pokémon, several more restrictions are put in place. The Player may not remove the shiny starter Pokémon from the active party while it is still conscious, and must never let it faint without being revived by a reviver seed. If it faints, it is no longer eligible to be transferred to the Player's story save, but at that point may be sent to assembly to make room for another member.
If the dungeon is later cleared by another member, all other team members may still be transferred, with only the shiny starter Pokémon being excluded. Any other shiny Pokémon recruited over the course of the dungeon do not face these limitations.
Scoring

After either clearing the dungeon or being defeated, a replay of the run will be saved and the Player will be presented with their final score. The Player's score is a combination of their Money on hand as well as the total value of all items currently in their bag. Some dungeons may also have a bonus score, which is added to the final score if a specific condition is met.
While the game keeps track of how long the run takes, time is not included in the Player's score.
