Given by the royalty to specially honor a person for service to the Kingdom above and beyond the call of duty. Each augmentation is a specific charge at the Crown's discretion, to be added to the individual's heraldic arms. This honor is infrequently granted. The specific charge is determined by the crown giving the award, frequently symbolic of the service done such as a spear for a champion or a candle enflamed for someone who has served the arts and sciences.

An honor added to a registered device. First, the Crown of a kingdom must give the recipient of the augmentation the right to add a charge or charges to a registered device as an honor, then the honor must be registered with the College of Arms. An augmentation is not registered as a change of armory; instead, both the underlying arms and the arms with augmentation are protected. Therefore, the underlying armory can be changed while keeping the augmentation the same (assuming no style problems result). Augmentations are usually registered by the College of Arms in the form "[Blazon of device], and as an augmentation, [blazon of augmentation]".
