You follow a monastic tradition that teaches you to harness the four elements through your connection to the natural world from the understanding of its functions. When your focus your Ki you can align yourself with the forces of creation and bend the four elements to your will, using them as extensions of your body and mind. Some members of this tradition dedicate themselves to a single element whereas other weave all elements together.

 

Many monks of this tradition tattoo their body with representations of their Ki powers, commonly imagined as coiling dragons, but also as phoenixes, fish, plants, mountains, clouds and cresting waves.

Elemental stances

When you choose this tradition at 3rd level, you learn four basic stances which allow you to manipulate one element to maximum efficiency. A stance requires a short rest to equip and only one stance can be equipped per short rest (until level 17 in monk when changing stance is a bonus action).

• Fire Throws: 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 by 10 feet for that action as well as the rest of your turn your unarmed attacks real fire damage and unarmed attacks done in that action deal an additional 1d10 Fire damage. You can spend an additional Ki point to add 1d10 fire damage to your flurry of blows after an attack was made as your action. 
• Water Whip: You can spend 1 Ki point on an action to create a whip of water that shoves and pulls a creature to unbalance it. A creature that you can see within 30 feet of you must make a dexterity saving throw. On a failed save, the creature takes 2d10 cold damage and is pulled or shoved 15 feet in a direction of your choice. On a successful save the target takes half damage and is not pulled.
• Earth Pillars: you can spend 1 Ki point as an action to create a number of stone pillars equal to your wisdom modifier in any free five foot unoccupied space. Each pillar is ten foot high and provides 1/2 cover to medium and smaller creatures. Each pillar has an AC of 15 and an HP of 15 open reaching 0 HP it crumbles into nothing. You can use an unarmed attack to shoot a block of stone in toward a target within 30 feet of the pillar as a ranged attack dealing 1d10 bludgeoning damage
• Air Whirlwind: As an action you can use you action to spend 1 Ki point to send a blast of air in a cyclone around you in a 10 foot radius around you. All creatures within the area must make a dexterity saving throw. On a failed save the creature takes 1d10 bludgeoning damage and is pushed 10 feet. On a successful save they take half the damage and are not moved back. After using this action you can jump your unarmored movement in height and distance without provoking attacks of opportunity. Furthermore, the air around you propels your body allowing you’re jump distance and height to be tripled.
