Way of the Raging Storm

Clap of Thunder
Starting when you choose this tradition at 3rd level, you can create claps of thunder from your furious blows.

Whenever you hit a creature with one of the attacks granted by your Flurry of Blows, you can spend 1 ki point to deal an additional 2d6 thunder damage. In addition, creatures of your choice within 5 feet of the target must make a Constitution saving throw. On a failed save, the creatures take 2d4 thunder damage.

Storm-charged
At 6th level, your unarmed strikes become like the storm. Whenever you hit with an unarmed strike, you can spend 3 ki points to cast shatter, centered on the target of your attack. You and a number of creatures you choose up to your Wisdom modifier are immune to its effects. In addition, you can spend 1 ki point to cast lightning lure as an action using your monk level.

Sparking Strike
At 11th level, you gain the ability to unleash bolts of lightning at your foes. On your turn, you can spend 4 ki points to cast the lightning bolt spell.

You can spend additional ki points to cast lightning bolt as a higher-level spell. Each additional ki point you spend increases the spell’s level by 1. The maximum number of ki points (2 plus any additional points) that you can spend on the spell equals half your monk level.

Lightning Strikes Twice
At 17th level, lightning courses through your veins, striking out at your foes. When you are hit by an attack, you can spend 6 ki points to be struck by lightning as your reaction. When you are struck with lightning, your unarmed strikes do an additional 4d8 lightning damage until the end of your next turn. In addition, creatures within 15 feet of you must make a Dexterity saving saving throw. On a failed save, they take 8d8 lightning damage and cannot take reactions for the next round. On a successful save, they take half damage, and do not lose their reactions.
