Way of the Dragon/Sun Soul

Monks of the Way of the Dragon Soul learn to channel their own life energy into searing bolts of light. They teach that meditation can unlock the ability to unleash the indomitable light shed by the soul of every living creature.

Radiant Sun Bolt

Starting when you choose this tradition at 3rd level, you can hurl searing bolts of magical radiance.

You gain a new attack option that you can use with the Attack action. This special attack is a ranged spell attack with a range of 30 feet. You are proficient with it, and you add your Wisdom modifier to its attack and damage rolls. Its damage is radiant, and its damage die is a d4. This die changes as you gain monk levels, as shown in the Martial Arts column of the Monk table.

When you take the Attack action on your turn and use this special attack as part of it you can spend 1 ki point to make the special attack twice as a bonus action.

When you gain the Extra Attack feature, this special attack can be used for any of the attacks you make as part of the Attack action.

The range of this attack scales with your unarmoured movement bonuses. 

You also learn the Dancing Lights cantrip. 

Searing Arc Strike

From 3rd level, when you take the Attack action on your turn, you can replace one of the attacks with a blast of energy in either a 20-foot cone or a 30-foot line that is 5 feet wide (your choice). Each creature in that area must make a Dexterity saving throw against your ki save DC, taking fire damage equal to 1d8 + your wisdom modifier on a failed save, or half as much damage on a successful one. When you reach 5th level, this increases to 2d8 + your wisdom modifier.

You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest. While you have no uses available, you can spend 2 ki points to use this feature again.

Starting at 6th level, You can also spend ki points to increase the damage of this ability. Each ki point you spend adds one additional d8 damage die. The maximum number of ki points that you can spend on this ability (including the initial 2 ki point cost, or assuming this if you are not spending ki to use this ability) equals half your monk level.

At 11th level, the base damage of this feature increases to 3d8 + your wisdom modifier.

At 17th level, the base damage of this feature increases to 4d8 + your wisdom modifier.

Radiant Soul

Starting at 6th level, you can use your bonus action to unleash the radiant energy within yourself, causing your eyes to glimmer and your body start to glow with burning fury.

• Your transformation lasts for 10 minutes or until you end it as a bonus action, or are incapacitated. During it, you have a flying speed equal to your movement speed, shed bright light in a 10-foot radius and dim light for an additional 10 feet.
• Whilst this transformation is active, once during each of your turns when you hit with an attack roll you can deal extra radiant damage to the target equal to one roll of your martial arts die.
• Once you use this trait, you can't use it again until you finish a short rest.

Searing Sunburst

At 11th level, you gain the ability to create an orb of light that erupts into a devastating explosion, or generate a devastating energy beam.

As an action, you magically create an orb and hurl it at a point you choose within 150 feet, where it erupts into a sphere of radiant light for a brief but deadly instant. Each creature in that 20-foot-radius sphere must succeed on a Constitution saving throw or take 2d6 radiant damage. 

Alternatively, you can emit a beam of energy that blasts out from you in a direction you choose 100ft long and 5ft wide. Each creature in line that is not behind total cover must succeed on a Constitution saving throw or take 2d6 radiant damage.

A creature doesn’t need to make the save if the creature is behind total cover that is opaque. You can increase the sphere’s damage by spending ki points. Each point you spend, to a maximum of 3, increases the damage by 2d6.

If you spend any ki points to use this ability, creatures that succeed on their saving throw take half-damage, instead of no damage. 

Sun Shield

At 17th level, you become wreathed in a luminous, magical aura. You shed bright light in a 30-foot radius and dim light for an additional 30 feet. You can extinguish or restore the light as a bonus action.

If a creature hits you with a melee attack while this light shines, you can use your reaction to deal radiant damage to the creature. The radiant damage equals 5 + your Wisdom modifier.

When you activate your Radiant Soul transformation, Radiant Fury explodes from you. Choose any number of creatures you can see within 30 feet of you. Each of those creatures must succeed on a Constitution saving throw against your ki save DC or take 5d10 radiant damage. In addition, creatures that fail this saving throw are blinded until the start of your next turn. Creatures that succeed on the saving throw only take half damage.
