Empty Body
18-Level Monk Feature
Beginning at 18th level, you can use your action to spend 5 ki
points and gain the benefits of Greater Invisibility for 1
minute. During that time, you also have resistance to all
damage but force damage.
Additionally, you can spend 4 ki points to cast the astral
projection spell, without needing material components. When
you do so, you can take up to eight willing creatures within
10 feet with you to the Astral Plane.
Once you use these features, you must finish a short or long
rest before you can use them again.
