Way of the Four Elements (But it's Avatar)

Elemental Attunement - 3rd level
You can use your action to briefly control elemental forces nearby, causing one of the following effects
Create a harmless, instantaneous sensory effect related to air, earth, fire or water, such as a shower of sparks, a puff of wind, a spray of mist, or a gentle rumbling of stone.
Instantaneously light or snuff out a candle, torch, or campfire.
Freeze or ignite up to 1 pound of nonliving material within 5 feet.
Cause earth, fire, water or mist that can fit within a 1-foot cube to shape itself into a form you desire for 1 minute.

Elemental Control - 3rd level
You learn to open yourself to the elemental forces and shape them with  your ki. You choose one element when you take this tradition. You gain an additional element at 6th, 11th and 17th levels. Elemental Control cannot be used while restrained.

Creatures who would be harmed by your elemental shaping can make a Dexterity saving throw.

You gain the following benefit, no matter which element you choose:
You can spend 1 ki point to make an unarmed strike with a range of 30 feet.

Earth
You can spend 1 ki point to permanently raise/lower/shape a 5-foot cube of earth or stone. You can spend up to your Wisdom modifier in ki points to extend the effect ex to make a 10-foot tall pillar or a 15-foot long wall.
You can use your reaction and spend 1 ki point to increase your AC by 3 against an attack you can see.
Fire
You are resistant to fire damage.
You can use your reaction and spend 1 ki point to make an retaliatory unarmed strike when you are hit by an attack.
Air
When you Dash or Disengage, your movement speed becomes a flying speed. If you end your turn in the air, you fall to the ground.
When you use Slow Fall, you take no falling damage.
Using Deflect Missiles to make a ranged attack no longer costs ki.
Water
You can spend 1 ki point to shape/freeze a 5-foot cube of water for 1 round. You can spend up to your Wisdom modifier in ki points to extend the effect. If you spend an additional ki point, you can maintain the shaping with concentration.
When you use Flurry of Blows, you can spend an additional ki point to make two additional unarmed strikes.
