Dimensional Rift

You have gained powers from the dark dimension and can thus move through them at will. At 4th level you can move through a self created Dimensional rift up to 80ft. when reappearing you do not make a sound and have advantage on stealth checks. Distance increases by 10ft every 2 levels. At the 8th level you can take up to 5 willing creatures through the rift. Moving more than 5 will result in you taking 1d4 force damage per creature per 10ft moved.
