Ethereal Shunt

You can use your reaction when you take damage to temporarly jump into the ethereal plane.

The damage triggering the effect is halved. You reappear at the end of your next turn in the space you occupied previously. If you occupy the same spot as a solid object or creature when this happens, you are immediately shunted to the nearest unoccupied space that you can occupy and take force damage equal to twice the number of feet you are moved.
