The cube can be moved and swiped into different configurations. When called upon, the cube floats and shines before changing and shifting to the perfect combination. What magical potential could be held within such an artifact?

The Gift of Alacrity. As an action, the creature who uses it adds 1d8 to their initiative rolls for eight hours. The casting time is 1 minute and the Gift of Alacrity recharges at dawn.

Magnify Gravity. As an action, you create a 10ft radius sphere within 60ft and gravity intensifies. All creatures within the 10ft radius are forced to make a DC14 CON Save or take 2d8 Force damage and their speed is halved until the end of their turn. On a success, the creature(s) takes half damage with no reduction in speed. Once used, Magnify Gravity may not be used again until the next dawn.
