Cavalier orders and increased levels for challenge

[Chess Pwn]

The

champion's banner:

A champion's banner is a cloth flag or standard (typically 2 feet wide and 4 feet long) meant to be carried and displayed on a lance, polearm, frame, or staff. It has no effect unless it is mounted properly and a wielder is carrying the object bearing it. It depicts the insignia or heraldic symbol of its wielder; if the wielder has no such symbol, it depicts a heraldic lion.

A character with the challenge class feature carrying a champion's banner treats his class level as 4 levels higher when determining the effect of his challenge ability. This does not alter the number of times per day the wielder may use his challenge ability, only the value of the bonuses it grants when he does so.

increases the cavalier's level for challenge. Does this also effect the challenge bonus that your order gives, like in the order of the land?

Whenever an order of the land cavalier issues a challenge, he receives a +1 morale bonus on ranged attack rolls against the target of his challenge. This bonus increases by +1 for every four levels the cavalier possesses.

Yes, Challenge is a two-part ability with one part located in the core Cavalier rules and the other part located in whichever Order you are a member of.

Each cavalier’s challenge also includes another effect which is listed in the section describing the cavalier’s order.

Furthermore, the challenge ability in each order is called "Challenge".
