Dragonblood Wreath

A burst of draconic energy bursts into existence from your body, swirling and twisting dangerously. At the end of each of your turns, any enemy adjacent to or sharing your space must succeed on a saving through or take 3 (1d6) points of damage matching your draconic ancestry or breath weapon's damage type. Additionally, your melee attacks deal an extra 1d6 points of damage of the same damage type.

A dragon capable of casting 5th level spells can cast this spell as a bonus action. Only dragons and creatures with draconic ancestry or boons can cast this spell.
