Myrmidon

Like the heroes of ages past, you learn to fight unencumbered by armor, instead relying on your innate speed and agility to grant you the following benefits: • While unarmored, your Armor Class equals 13 + your Dexterity modifier. You can use a shield and still gain this benefit. • While unarmored, damage you take from nonmagical bludgeoning, piercing, and slashing damage is reduced by an amount equal to your Dexterity modifier.
