Often followers of gods who hold domain over storms and seas these monks can often be found aboard ships attempting to calm the storms their ship sails through or even call storms upon other ships.

When you take the dodge action or use your patient defence you ready a counterattack for any who dare to strike at you. While dodging if you take damage from a target within 20ft of you you can use your reaction to force the target to make a dexterity saving throw, DC is equal to 8 + proficiency bonus + wisdom modifier, on a failed save the target takes lightning damage equal to one roll of your martial arts die or half on a success.
