Monks of the Way of The Saiyan learn to manipulate their life energy into magic and power.

Monks of the Way of The Saiyan tend to be aggressively militant, they share an innate enjoyment for conflict and fighting, choosing violence over peace with others. They are typically very aggressive and hard-headed, with short explosive tempers. Monks of the Way of The Saiyan appear inclined to be arrogant at times, leading them to allow enemies to gain advantages in battle just for fun. It appears they have a tendency to let their emotions get the better of them when roused in stimulating situations, resulting in them at times making rash decisions.

Monks of the Way of The Saiyan study and adhere to a code of combat and pride. They seek out challenges and worthy adversaries in order to become the best fighter they can possibly be. Sometimes these monks can be found in collectives in a monastery, continually competing to be defeat one another. However, on many occasions these monks set out on their own to find and do battle against the most powerful foes throughout the realms. 

Saiyan Ki Techniques

Starting when you choose this way at 3rd level, you can use your ki to duplicate the effects of certain spells. As an action, you can spend a number of ki points equal to the spells level in order to cast the spells granted to this subclass, without providing material components or an arcane focus. These spells can only be cast at the corresponding level outlined in table and can only target yourself. Any saving throws that may be required by any of these spells are made against your Ki save DC. 

Way of The Saiyan Spells

Battle-Hardened Mind

Upon reaching 6th level, you have concentrated on spells while in close quarters combat that you now have proficiency in constitution saving throws in order to maintain concentration. 

Kaioken

At 6th level, you have learned how to manipulate. Now, as a bonus action, you can gain a level of exhaustion in order to regain Ki Points equal to your proficiency bonus.

Super Saiyan Transformation

Once you reach 11th level, your mastery of Ki has allowed you to push beyond your natural limits. Once per long rest, as a bonus action, for one hour, you can wreath yourself in a luminous, magical aura that sheds bright light in a 30-ft. radius and dim light for an additional 30 ft., and you can concentrate on two spells at once.

Kamehameha

Starting at 17th level, your touch can channel your ki energy into a beam of bright blue energy.
As an action, you touch one creature within 5 feet of you, and you expend 10 ki points to create a beam of brilliant light flashes out from your hand in a 5-foot-wide, 60-foot-long line. Each creature in the line must make a Constitution saving throw. On a failed save, a creature takes 10d10 radiant damage and is blinded until your next turn. On a successful save, it takes half as much damage and isn't blinded by this spell.
