Ki Blast

As an action, you can expend any number of ki points to channel that mystical energy into a devastating blast.

You let loose a beam of force 5 feet wide and 30 feet long. Any creatures in the area of effect must make a Dexterity saving throw, taking 2d6 force damage on a failed save, or half as much on a success. For each ki point you expended beyond the first, increase the damage dealt by 1d6.

If you expended 6 or more ki points to use this feature, you can increase the size of the effect. Either the size of the beam increases to 10 feet wide and 60 feet long, or you can let loose the energy as a pulse that strikes all other creatures in a 15-foot radius.

If you expended 20 or more ki points to use this feature, those in the area of effect automatically fail the dexterity saving throw, and are also paralyzed until the end of your next turn.
