β‘ Quick Strategy (TL;DR)
Push the boss to remove his invulnerability, but be careful not to end your turn in line with him when doing so.
The first time you do the dungeon, the quest "Antiroyaliste" will start automatically. It is one of the two quests required to use the Frigostian transport to reach Alma's Cradle (the second starts automatically when you do the "Excavation du Mansot Royal" dungeon for the first time).

Dungeon mechanics
Be very careful about lines when moving it, especially the abandoned Sram traps.
The dungeon itself is not very complicated, but if you want to complete all the challenges, you will need to stay focused!
