Isawa Natsune: Phoenix Clan Librarian. Shugenja Natsune may hold any number of spells. Natsune may not bow to produce spell effects. All spells being attached to Natsune have their gold cost reduced by four.
Phoenix Clan Scribe. Shugenja May not bow to produce spell effects. Limited: Bow to retrieve a spell from any player's discard pile and attach it to Togama. Cost must be paid normally. Togama may not retrieve any spell card more than once.
Do the bolded texts mean that they are uncapable of paying the costs of a spell that has "bow this shugenja" as a cost or that they may waive the cost of bowing? Thank you in advance.
