The Royal Regimen

The Royal Regimen is a tutorial-like series of Endeavors that teaches how to play Dragalia Lost.

Overview
The Royal Regimen's endeavors give tasks that guide the player through basic progression and game mechanics in Dragalia Lost. These include completing the Main Campaign; upgrading adventurers, facilities, and equipment; and completing late-game content such as standard-mode High Dragon Trials and The Agito Uprising.

These tasks act mostly the same as regular Endeavors, but are in a separate menu and must be completed in sequence. If, for example, the player has completed the task for endeavor #10, but they have not yet completed endeavor #9, then they cannot claim their prize for completing endeavor #10 until after they have also completed endeavor #9.

Each endeavor will also have an extended description with more details about the task, as well as a "Go" button that will take the player to a menu relevant to the task - for example, an endeavor requiring progress in the Main Campaign will go to the Main Campaign screen.

The endeavors are divided into three stages: Basic, Intermediate, and Advanced Drills, and these are sequential in the same way as the endeavors themselves. Stage 1 must be completed before advancing to stage 2, etc.

The Royal Regimen's endeavors will apply retroactively for players who had completed tasks before entering the Regimen's menu. However, there are a couple of exceptions to this:
 * "View the Wyrmprint Section of the Treasure Trade" - requires the player to visit that section again, regardless of whether they have accessed it before.
 * "Obtain Glorious Tempest from the Treasure Trade" - if the player has never obtained Glorious Tempest through Treasure Trade specifically, but instead by other means, such as the March 2020 Catch-Up Campaign endeavors. In such a case, redeeming an additional copy of the Wyrmprint from Treasure Trade will complete the endeavor.

Notable rewards include a total of x4,  x3, and  x4,400. Most of the other rewards are upgrade materials, positioned in such a way to speed up completion of the Royal Regimen itself.

The Royal Regimen is accessible via a window on the home screen before the entire regimen is complete. After completion, the window will disappear. The player may go back to view the endeavors under More (Green Book) → Player Info.
