Last-Ditch Effort
A Brightnose has to defend its rank against many competitors, and this constant duelling has honed your reflexes to sharpen when the end of the fight draws close. When you are reduced below half your maximum hit points, you gain +1 AC and have advantage on Dexterity saving throws for 1 minute. Once you use this trait, you cannot use it again until you have finished a long rest.
