Fist of the BStar

By following the path of The Fist of the BStar, you enhance your control, as well as your power, of Ki, allowing you to perform feats of unimaginable strength, such as shockwaves with every punch, or teleporting away from incoming attacks.  By the end of your journey through this path, you will have complete control over your Ki, allowing you to spare your Ki usage with many added benefits.

Shockwave Punch

Every unarmed attack that hits something (doesn't have to be an enemy) sends a shockwave in a spherical radius, with the distance of the radius being 10 × (Str Mod + 1).  Every creature in range must make a Strength saving through with a DC of 13.  If it succeeds, it takes half damage, otherwise it is knocked prone.  Damage is a 3d12 + Str Mod + Dex Mod + Proficiency.

At levels 5, 8, 12, 17, and 20, the damage dice is increased to 5d12, 8d12, 10d12, 20d12, and 50d20 respectively.

Blink Teleportation

As a reaction, you can spend 1 ki to teleport out of the way of an incoming attack, up to your max movement speed away in any direction. This can be done either before or after the hit throw is made, but not after the damage roll. The attack that would have hit misses entirely, even if it was a natural 20.  This can be done only once per round.

Critical Overload

Whenever you connect with an unarmed attack, you can spend 1 ki to make it a critical hit, doubling damage, or 2 ki to triple damage. This must be decided to be used after the roll to hit, but it can wait to be decided until after the damage roll, so long as the DM has yet to hear the result of the damage.

Ki Control

Now having complete mastery of controlling your ki, all ki costs are lessened by 1, and any that cost 1 now cost nothing.

As a bonus to this, because of Ki keeping your body in peak physical condition, you also get +20 to all stats, gain 5 chosen feats, 5 additional proficiencies, and 11 total extra attacks every turn.
