Path of Draconic Blood

At level 3 when you select this subclass, your dragon blood allows you to grow to Large size when you rage, and you are allotted a pool of four Soul Points to use in battle, those soul points allow you to use draconic actions like Rend, Fire Breath, and Multi Attack, using 1 soul point per draconic action. At a Large size, all damage dealt from an unarmed attack or natural weapon is increased to 1d10 plus your strength modifier if not already higher than that. 

At level six your heart burns with anticipation as you unleash a Blazing Aura any time you rage, surrounding yourself and your weapons in magical flames, granting you immunity to fire, and adding an additional 1d6 fire damage to any attack you make. As your blood boils during a rage you can sprout draconic wings from your back with a flight speed equal to your base walking speed. With such a powerful aura emanating from your presence, you gain the ability to use a draconic action to Frighten your enemies, forcing anyone who can see you within 30 ft to make a wisdom saving throw, or be terrified of your power. 

At level 10 you’ve become so in tune with your draconic powers you now have what is called Searing Presence, increasing the fire damage dealt by Blazing Aura from 1d6 to 1d8. Using the searing energy coming off of your skin, you can use a draconic action to erupt into a flaming sphere centered around yourself, dealing 4d6 fire damage to anything within 5 ft of you. Just as your blood continues to boil with the chaotic power of a red dragon, your soul continues to learn ancient draconic secrets hidden deep inside yourself; you can cast detect magic at will outside of battle without using any spell slots or soul points. Additionally, you may use draconic actions to cast command, scorching ray, and fireball, using charisma as the spellcasting ability for the spell save DC. Your pool of Soul Points also increases to 7.

You gain 4d12 temporary hp for the duration of your rage, and unlock the Pounce and Tail Bludgeon Draconic Actions. Your Pool of soul points is also increased to a total of 10.
