Not really clear at all. They get an extra three weapon proficiencies and two non-weapon proficiencies when they first become a Knight of the Rose at level 4. It says they advance more slowly than others because of their greater training but they advance farther than others. The only mechanical benefit thing I see though is the extra initial proficiencies.
The Knights of the Rose gain special proficiencies in weapons and combat. While they advance more slowly than other Knights (because of the great amount of training and skill required by their proficiencies). they also can advance farther than any of the other
Knighthoods.
Proficiencies Weapon I Non weapon
Initial * 3/2
Added 2/1 per 2 levels
* The Initial Proficiencies listed here are in addition to those proficiencies already obtained. In other words, during the Knight's initial training period in the Order of the Rose, he acquires three additional weapons proficiencies and two additional nonweapon proficiencies on top of any already received as a Knight of the Crown and as a Knight of the Sword.
