Cursekeeper Sphere

The Cursekeeper Sphere is a mysterious magical trinket created by an enigmatic sorcerer. It takes the form of a small, 3x3x3 rubik's sphere, each side of the sphere bears intricate arcane symbols representing different curses. The sphere has the power to prepare up to three curses at a time, each activated by a unique combination set by the user. Once set, the curses can only be activated or deactivated by those who know the secret combination. Curses can be changed once after a long rest. 

Activation:

To activate the Cursekeeper Sphere, the user must manipulate the cube's sides in a specific sequence. Use an action to turn the sides in the right order. The sequence can be any combination of rotations and orientations of the sides, such as turning the top row to the left, middle row to the right, and bottom row upwards, etc. The sequence can be as simple or complex as the user desires, as long as it is unique.

The user must perform the chosen sequence with intention and concentration. Once the correct combination is completed, the corresponding curse is activated. The user can activate one curse at a time or multiple curses simultaneously, depending on how many curses the sphere currently holds. 

Deactivation:

Deactivating a curse is done in the same manner as activation. The user must use an action to perform the reverse sequence of the curse they wish to deactivate. If a curse is activated with a specific sequence, the same sequence must be used to deactivate it. If the user wishes to remove all curses, they can perform a specific sequence that clears the sphere, resetting it to its default state.
