Weekly Boss

Weekly Bosses are bosses whose rewards can be claimed once per week. After defeating each boss, a Trounce Blossom will spawn where players can choose to spend to claim the rewards from the first three weekly bosses of their choice, and then subsequently. Availability of rewards and reduced resin costs reset at 4 AM server time every Monday.
Weekly Bosses are generally fought in a Trounce Domain (thus players can teleport to them) apart from Andrius, who is fought in the open world. These bosses are unlocked by completing Archon Quests or a specific character's Story Quest. Once the player reaches Adventure Rank 40, they can Quick Challenge locked Trounce Domains through the Adventurer Handbook in Single Player Mode if they have not met the requirements to normally access it.
