Feat: Dragon Transformation

You transform into a ferocious Large dragon, gaining the effects of 6th-rank Dragon Form except that you use your own AC and attack modifier, you apply your extra damage from Rage, and the Dragon Breath action uses your class DC. Add the temporary Hit Points from dragon form to any you already have from entering a rage (or any other action with the rage trait). The action to Dismiss the transformation gains the rage trait.

At 18th level, you gain a +20-foot status bonus to your fly Speed, your damage bonus with dragon Strikes increases to +12, and you gain a +14 status bonus to your Dragon Breath damage.
