After completing the Arator’s Journey campaign, you unlock access to the Arcantina. You obtain the Arcantina key in your Toy UI and can teleport there with an 8-minute cooldown. The Arcantina will have 1-2 new quests for you each week. At the end of each quest, your reward is a Decor. That Decor item is also placed somewhere inside the Arcantina as a permanent trophy, and it is interactive with a bit of lore flavor text.
