Draconic Communion

The caster consumes dragon's blood, gaining traits based on the type of blood they consumed.
The caster is granted 60ft of flight, resistance to the element that the dragon's blood corresponds to, and a breath weapon akin to that dragon for the duration of the spell.
Along with the wings, the caster may also gain some other physical traits based of the dragon, including some scales, claws, and a tail. Making an unarmed strike with these will deal damage equal to 1d6 + Str modifier

(For reference)

At Higher Levels:

The spell duration is increased by 1 minute for every level the user upcasts the spell by.

From level 7 and up, the user instead gains immunity to the element of the dragon's blood, along with the previous bonuses.
