2022 Ghost Key Chests were unlockable for Ghost Keys for various prices corresponding to the rarity of potential items in the 2022 Halloween Event. The layout was different then other Boss Chest Layouts with a 3, 30, and two 350 Key Chests.
In the v1.119.0 update, the original two 350 Key Chests moved to the left of the tower platform, making room for two new 350 Key Chests on the right side.
