Mistly Escape

You can vanish in a puff of mist in response to
harm. When you take damage, you can use your reaction to turn invisible and teleport up to 60 ft.
to an unoccupied space you can see. You remain
invisible until the start of your next turn or
until you attack or cast a spell.
Once you use this feature, you can't use it again
until you finish a short or long rest.
