Accolade Attribute
The game also links it as Accolade Attributes.
From the game's encyclopedia
An Accolade has up to 3 Attributes, which provide scaling bonuses as their higher levels are unlocked. Each Attribute has 3 Levels. When an Accolade increases its Accolade Rank, its owner may either increase the level of an existing Attributes or add a new Attribute to the Accolade. The Acclaimed Knight, however, must satisfy any new Attribute's requirements.
Each Knight is only eligible for certain Attributes, which may be based on Traits, Skills or experiential unlocks while serving as a Knight.
Every Accolade must have unique Attributes: a Liege cannot duplicate Attributes between Accolades. Each Accolade may also specialize in only 1 Men-at-Arms-type Attribute.
