Way of the Storm

Monks of the Way of the storm attune themselves to the natural energies of a storm's essence.  They learn to manipulate these energies in ways that allowing them to make their movements around the battlefield more chaotic, call out to the storms energy to aid them, or even become a element of the storm themselves.

Ride the Lightning

Starting when you choose this tradition at 3rd level, you can spend 2 Ki points as an action to briefly become an entity of pure lightning energy, allowing you to pass through other creatures causing an surge of lightning to erupt through them causing lighting damage.  Any creature whose space you pass through in this way must make a dexeterity saving throw equal to 8 + your wisdom + your proficiency. On a failed save each creature takes lightning damage equal to your Martial arts die + your wisdom modifier, or half as much on a success. Your movement is unaffected by difficult terrain, and spells and other magical effects can neither reduce your speed nor cause you to be paralyzed or restrained, until the start of your next turn.

You can also spend 5 feet of movement to automatically escape from nonmagical restraints, such as manacles or a creature that has it grappled. Finally, being underwater imposes no penalties on the your movement or attacks while using this feature.

One with the Storm

At 3rd level, you have become more attuned to the storm, gaining the following:

• You gain proficiency in the Nature skill
• You gain the ability to breathe Water
• A Swim speed equal to your walking speed
• Resistance to Lightning and Thunder damage

Storm's Guidance

Beginning at 6th level you gain the ability to commune with the storm.  Speding 2 ki points you can briefly become one with the storm and gain knowledge of the surrounding territory. In the outdoors, this feature gives you knowledge of the land within 10 miles of you.  This ability has no effect where the storm can not reach as in caves, dungeons, or underground.  When in stormy conditions you gain addition benefits (GM's approval) up to and including honing in on a conversation being made.

You instantly gain knowledge of any facts of your choice about any of the following subjects as they relate to the area:

• terrain and bodies of water
• prevalent plants, minerals, animals, or peoples
• powerful celestials, fey, fiends, elementals, or undead
• influence from other planes of existence
• buildings

For example, you could determine the location of powerful undead in the area, the location of major sources of safe drinking water, and the location of any nearby towns.

Storm's Herald

Starting at 6th level you as action can spend 3 Ki points to Call Lightning from yourself for up to 1 minute.  You concentrate for 1 minute or can end it early as a free action. A bolt of lightning flashes from you in a 30 ft line 5 foot wide blast. Each creature must make a Dexterity saving throw. A creature takes 3d10 lightning damage on a failed save, or half as much damage on a successful one. On each of your turns until the effect ends, you can use your action to call lightning in this way again, targeting the same point or a different one, this does not use more Ki points. You can also spend additional Ki points to enhance this ability.  This affect increases by 1d10 for each addition Ki point you spend up to 2 additional points.  5 being the maximum you can spend making it 5d10

If you are outdoors in stormy conditions when you cast this spell, the spell gives you control over the existing storm instead of creating a new one. Under such conditions, this features damage increases by 1d10.

In addition when you use this action on your turn you can use a bonus action to make an unarmed strike or spend 1 ki point to do a Flurry of Blows.
