When you hit with one of these unarmed strikes, you can spend 1 ki point to push the target up to 20 feet away from you or pull the target up to 20 feet toward you.

Earth Bending

You gain the Mold Earth cantrip. At the start of your turn, you can turn part of your body to stone. Your unarmed strikes deal an additional 2 bludgeoning damage for the rest of your turn. When you hit with one of these unarmed strikes, you can spend 1 ki point to force the target to make a Strength saving throw against your ki DC or be knocked prone.

Fire Bending

You gain the Control Flames cantrip. At the start of your turn, you can imbue your unarmed strikes with flames. Your reach with your unarmed strikes increases by 10 feet for the rest of your turn. When you hit with one of these unarmed strikes it deals fire damage instead of bludgeoning damage, and you can spend 1 ki point to deal an extra fire damage equal to 1d10+your Wisdom modifier.

When one of these strikes hit, you can spend 1 ki point to force the target to make a Dexterity saving throw against your ki DC, on a failure the target is grappled until the end of your next turn.

Elemental Arts

When you choose this tradition at 3rd level, you learn to manipulate the ki flowing through the world to magically bend elements to your will. You learn one elemental art of your choice, you learn one additional elemental art of your choice at 6th, 9th, 12th, 15th, and 18th level. Whenever you learn a new elemental art, you can also replace one elemental art that you already know with a different elemental art.

Casting Elemental Spells

See the Spellcasting section for the general rules of spellcasting, you can replace all the attacks you make with your Attack action with a casting of one of these spells.. You can cast each of these elemental spells once at its lowest level without expending ki points, regaining the ability to cast it this way when you finish a long rest. Alternatively, you can spend ki points to cast the spell, spending extra ki points to increase its level by one for each additional ki expended. You can spend a maximum number of ki points equal to your proficiency bonus on a single casting of a spell. These spells use your Wisdom as your spellcasting ability modifier, you do not need any material components when you cast these spells.

At 17th level, as an action you can spend 5 ki points to transform into an air elemental, water elemental, fire elemental, or earth elemental. You retain your saving throw proficiencies, your class features, and your alignment and personality while in this form. You can remain transformed for 1 hour, or until you choose to end it as a bonus action. Your hit points are replaced by the hit points of the elemental, when these are reduced to 0 or you die, you revert to your normal form and any excess damage is carried over to your normal hit points.
