Level 17: Might of the Moon

While in your Lunar Phase, you can use an action and expend up to 4 ki points to evoke the powers
associated with the phase:

Full Moon. You radiate a soothing wave of moonlight. Roll a number of Martial Arts die equal to the number of ki points you expent. Up to six creatures of your choice within 15 feet of you regain hit points equal to the rolled amount + your Wisdom modifier.

 New Moon. You evoke the shadows, blocking all light around you. Roll a number of Martial Arts die equal to the number of ki points you expent. Each creature of your choice within 15 feet of you must succeed on a Wisdom saving throw against your save DC or take psychic damage equal to the rolled amount, taking half as much on a success.

Gibbous Moon. You expand the light from your fists in a sudden burst. Each creature of your choice within 15 feet of you must succeed on a Strength saving throw against your save DC or be pushed away from you a number of feet equal to the number of ki points you expent x 5, being pushed half as much on a success. The area within 15 feet of you becomes difficult terrain for the chosen creatures until the start of your next turn.

Crescent Moon. You quickly swipe your arms or legs, creating a trail of light that travels ahead. Make a number of ranged attack rolls equal to 1 + the number of ki points you expent. Each attack has a range of 90 feet and deals one roll of your Martial Arts die + your Wisdom or Dexterity modifier slashing damage.
