No. The unit with the Peasant's Duty simply gets to use the Knight's own Leadership, as the Knights get to use the General's leadership, but they do not change their own leadership.

First both players deploy their armies. Then they both hide a dice under their palm - if they wish to pray, the dice must show a 6, if they do not wish to pray, it must show a 1. The dice are then revealed. If both players wish to pray, they both get the Blessing and then the game continues as normal (roll to see who goes first). If both players do not wish to pray, neither army gets the Blessing and then the game continues as normal (roll to see who goes first). If one of them wishes to pray and the other does not, the praying army gets the Blessing and the other (obviously the 'bad guys'!) does not get the Blessing, but gets to choose whether to go first or second.

No. The mount simply gets the normal Blessing saves.

The rider only.

No. Otherwise the words "Knights unit only" would be pointless (as only units of Knights and the Army Battle Standard Bearer can carry magic banners).

Yes.

No. Characters can never join a flying unit.

Yes.

No. Flying cavalry moving on the ground are limited by terrain as normal.

No. As they are skirmishers, they never truly 'form up into ranks'.
