Monks of the Anima Sol believe that meditation can unlock the ability to unleash the indomitable light shed by the soul of every living creature. They learn to channel their life energy into searing bolts, arks, or beams of light as well as other brilliant effects.

Soulcasting

Wisdom is your Spell Casting ability. 
Your Spell Save DC = 8 + Your Wisdom Modifier + Your Proficiency Bonus 
Your Spell Attack Bonus = Your Wisdom Modifier + Your Proficiency Bonus 

Lux Anima (Soul Light)

Starting when you choose this archetype at 3rd level, your Ki fills you with a bright inner light. You learn the Light and Dancing Lights Cantrips. You may cast these spells as a bonus action.

Radiant Sun Bolt Technique

Starting at 3rd level you gain a new attack option that you can use to replace any number of weapon attacks you make as part of the Attack action, or as part of any bonus action granted by the Martial Arts class feature or flurry of blows.
These special attacks are ranged spell attacks with a range of 30/60. You are proficient with them, and you add your Wisdom modifier to their attack and damage rolls. Their damage is radiant, and their damage die equals your Martial Arts die. These attacks may trigger the additional unarmed strikes granted by the Martial Arts Class Feature, or Flurry of Blows.

Starting at 6th level, because of your radiant Ki, you can empower your Radiant Sun Bolts with  even more blazing light. When you hit another creature with a Radiant Sun Bolt you can spend 1 Ki point to attempt a blinding bolt. The target must succeed on a Constitution saving throw or be blinded until the end of your next turn.

Searing Strike Techniques

At 6th level, you gain the ability to channel your Ki into searing waves of energy or other magical effects. When you gain this class feature, choose two of the following spells: A Grasping Light, Bolstering Light, Radiant Burst, Stunning Brilliance, Burning Hands, Color Spray, Divine Favor, or Faerie Fire. The damage type for Burning Hands changes to radiant and no material components are required to cast Color Spray. Whenever you gain a level in this class you may replace one of the Searing Strike spells you know with another Searing Strike spell.

You may spend 2 Ki to cast one of your Searing Strike spell as an action, or immediately after you take the Attack action on your turn you can spend 2 Ki points to cast one of your Searing Strike spells as a bonus action.

If your chosen Searing Strike spells can be cast at higher levels, whenever you cast those spells as part of this class feature you can spend additional Ki points to cast your Searing Strike spell at a higher-level. 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 rounded up.

Searing Sun Techniques

At 11th level, you gain the ability to channel your Ki into devastating energy attacks. When you gain this class feature you learn one of the following techniques: Searing Sunbeam, Searing Sunburst, or Searing Sunwave.

Searing Sunbeam Technique

As an action you may spend 1 Ki point to send a magical beam of light forming a line 60 feet long and 5 feet wide blasting out from you in a direction you choose.

Each creature in the line must make a Dexterity saving throw. A creature takes 2 Martial Arts Dice plus your Wisdom modifier in radiant damage on a failed save, or half as much damage on a successful one. A creature doesn't need to make the save if the creature is behind total cover that is opaque.

You can increase the line's damage and length by spending up to 3 additional Ki points. Each additional point of Ki you spend increases the damage by 2 Martial Arts Dice and the length of the line by 20 feet.

Searing Sunburst Technique

As an action, you may spend 1 Ki point to create a magical orb of light 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 5-foot-radius sphere must succeed on a Constitution saving throw or take 2 Martial arts Dice plus your Wisdom modifier in radiant damage, or half as much on a failed save. 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 and radius by spending up to 3 additional Ki points. Each additional point of Ki you spend increases the damage by 2 Martial Arts Dice and the radius of the sphere by 5 feet.

Searing Sunwave Technique

Sunshroud Technique

At 17th level you learn the Sunshroud technique. While your Sunshroud is active you shed daylight in a 20-foot radius, bright light for an additional 20 feet, and dim light for an additional 20 feet. If any of this class feature's area of daylight overlaps with an area of darkness created by a spell of 4th level or lower, the spell that created the darkness is dispelled.

While this light shines you:

• have disadvantage on Stealth checks while you are visible
• gain resistance to radiant and necrotic damage 
• your Unarmed Strikes deal Radiant damage instead of their normal damage type
• if a creature hits you with a melee attack that creature must succeed at a Dexterity Saving Throw or take radiant damage equal to your Wisdom modifier (minimum 1).
