how much honor will I gain if i bow an opposing card in battle with Isawa Emori with a Sisters of the elements attached to him and why?
Sisters of the Elements
Unique • Monk • Air • Earth • Fire • Water • Void
May only attach to a Monk, Shugenja, or Enlightened Personality. Once per turn, you may target or bow this card instead of this Personality as a cost for casting a Kiho.
Limited: Remove two cards in your hand from the game: Retrieve an Elemental Fate card from your discard pile.
Isawa Emori
Phoenix Clan Shugenja • Master of Earth
Battle: Bow a target card with no attachments opposing Emori. Gain Honor equal to the number of different Element traits in Emori's army

Five, by card text (Air • Earth • Fire • Water • Void = five different element traits in your army.)
