Vow of Kinship
Move all of your 
to the 
bank. Any you gain or take is put in the bank. You can use in the bank as if it is on your board.
Q: Do cards like $Royal Tax$ take favor from the Nomad bank now?
A: Nope. You can use favor in the Nomad bank, but it is not favor on your board.
Q: If I have the Banner of the People's Favor with only one favor, does its Wake power force me to take from the Nomad bank?
A: No. You can use Nomad favor as if it is on your board, but you are not forced to.
Q: If someone gives me favor, such as by using Witch's Bargain, does it go on my board or in the Nomad bank?
A: It goes to the Nomad bank. More accurately, the card should say ‘any favor going to your board’ instead of ‘any favor you gain or take.’
