Prerequisite: 17th Level.
As an action, you can spend 5 ki points to gain multiple benefits for 1 minute. While this ability is active, you gain resistance to bludgeoning, piercing, slashing, cold, fire, lightning, and thunder damage. You also gain a burrow, fly, and swim speed equal to your land speed. Lastly, you can use any of the following abilities as a bonus action:

You create a small earthquake on the ground in a 15-foot radius around you. Each creature in that area must make a Dexterity saving throw. On a failed save, a creature takes 1d8 bludgeoning damage and is knocked prone. On a successful save, the creature takes half as much damage and is not knock prone.

You create a line of fire 15 feet long and 5 feet wide that extends from you in a direction of your choice. Each creature in that line must make a Dexterity saving throw. A creature takes 3d6 points of fire damage on a failed save and halve as much on a successful one.

You create a 15-foot cube of swirling wind centered on a point you can see within 60 feet. Each creature in that area must make a constitution saving throw. A creature takes 1d10 bludgeoning damage on a failed save, and half as much on a successful one. If a Large or smaller creature fails the save, that creature is also pushed up to 10 feet away from the center of the cube.

You create a 15-foot cone of ice shards extending from you in a direction of your choice. Each creature in the cone must make a Constitution saving throw. On a failed save, a creature takes 2d6 cold damage and has its speed halved until the start of your next turn. On a successful save, the creature takes half as much damage and doesn't have its speed halved.

You can spend 5 ki points to cast Stoneskin, targeting yourself.    

Exploding Cinder Strike

Whenever you make an attack granted by your Flurry of Blows ability, you may replace it with an explosive strike. Your target and all enemies adjacent to it must make a Dexterity saving throw. On a failed save, an effected creature takes fire damage equal to your unarmed strike damage (including Strength or Dexterity modifier), or half as much on a successful save.    

Eyes of Fire

Prerequisite:
6th Level. As a bonus action, you can spend 2 ki points to gain magical heat vision with a range of 60 feet for 1 minute (with Concentration). This allows you to see any heat source in range, typically created by creatures or fire, revealing nothing else but the general size, location, and form of the heat source. Heat sources that would otherwise be invisible, hidden, obscured, or located on the other side of walls or barriers you could not normally see through are revealed with this vision. This vision cannot penetrate ice, snow, water, or magical darkness, nor can it detect creatures that do not produce heat, such as undead or constructs.    

Hungry Flames

Prerequisite: 11th Level.
Whenever you deal fire damage to a creature, that creature catches fire, if it has not already. A creature that has caught fire by this effect will continue to take fire damage equal to your Martial Arts die at the end of each of its turns for 1 minute. The fire can be extinguished through mundane means, such as water or a strong wind. A creature or an adjacent ally can also use an action to extinguish the flames affecting it, and creatures that were already on fire due to some other effect are immune to this effect.    

Hurricane Throw

You can treat simple thrown weapons as monk weapons for the purposes of Martial Arts. You may make attacks with simple thrown weapons in place of unarmed strikes when you use your Flurry of Blows ability.    

Iron Tortoise Shield

Prerequisite: 6th Level.
As a reaction, you can spend 2 ki points to use your Deflect Missiles ability against a ranged or melee attack you can see within 30 feet. Any damage not prevented by this ability is taken by the original target of the attack. If the attack's damage is reduced to 0 by this ability, you cannot spend 1 ki point to return the attack.    

Fangs of the Fire Snake

When you use the Attack action on your turn, you can spend 1 ki point to cause tendrils of flame to stretch out from your fists and feet. Your reach with your unarmed strikes increases by 10 feet for that action, as well as the rest of the turn. A hit with such an attack deals fire damage instead of bludgeoning damage, and if you spend 1 ki point when the attack hits, it also deals an extra 1d10 fire damage.    

Fist of Four Thunders

You can spend 2 ki points to cast Thunderwave.    

Fist of Unbroken Air

You can create a blast of compressed air that strikes like a mighty fist. As an action, you can spend 2 ki points and choose a creature within 30 feet of you. That creature must make a Strength saving throw. On a failed save, the creature takes 3d10 bludgeoning damage, plus an extra 1d10 bludgeoning damage for each additional ki point you spend, and you can push the creature up to 20 feet away from you and knock it prone. On a successful save, the creature takes half as much damage, and you don't push it or knock it prone.    

Flames of the Phoenix

Prerequisite: 11th Level.
You can spend 4 ki points to cast Fireball.    

Flowing Water Stance

Whenever you make an attack granted by your Flurry of Blows ability, you may immediately move an additional 5 feet, and you may also force your target to make a Dexterity saving throw (even if you do not succeed on the attack). On a failed save, your target is pushed 5 feet in any direction of your choice. Neither movement provokes an attack of opportunity.    

Freezing Stun Strike

The duration of your Stunning Strike ability is increased to 1 minute. At the end of each of its turns, it targets makes another Constitution saving throw. On a successful save, the effect ends on the target. This ability does not increase the duration of your Stunning Strike ability when it is used against a creature that has either resistance or immunity to Cold damage.    

Golden Snake's Icy Path

Whenever you take the Dash action, until the end of your turn, for any movement you make along a surface you can leave a path of slippery ice. This ice is considered difficult terrain and lasts a number of rounds equal to your Wisdom modifier (minimum 1). Also, any creature other than you that enters a space covered in this ice must make a Dexterity saving throw, falling prone on a failed save. If this ice covers a space that would normally be hazardous (such as acid or lava), then that hazard is ignored by creatures standing on this ice, but the duration of this ice is reduced by half, rounded down (minimum 1).
