Draconic Resilience
As magic flows through your body, it causes physical traits of your dragon ancestors to emerge. At 1st level, your hit point maximum increases by 1 and increases by 1 again whenever you gain a level in this class.
Additionally, parts of your skin are covered by a thin sheen of dragon-like scales. When you aren't wearing armor, your AC equals 13 + your Dexterity modifier.
