Shadow Step

Using your Psionic powers, roll 1d4 to see how many uses you have per long rest.

As a bonus action, you can teleport to a shadow up to 40 feet away. The shadow needs to be large enough to encompass the user's body(At least medium-sized(5x5) for living entities, at least large-sized(10x10) for non-living entities).
