Two-Gun Mojo. The section of the book dealing with using both hands at once is unclear and the example doesn’t match the stated rules. This is not a change. It is a clarification. So here it is, as simple as we can make it:

• a) Every character is considered to be either left or right handed. For ease of play, the character is usually considered to be the same handedness as the player. An ambidextrous player should choose an on hand and an off hand for their character.
• b) To do anything with the off hand (ie. the left hand for a right-handed character) is a two trait penalty. That means it costs THREE traits to perform an action with your off hand.
• c) The Merit Ambidextrous negates the two trait penalty for using your off hand, and ONLY that penalty.
• d) Each hand is considered an action. If you try to do two things at the same time, one with each hand, it is an extra trait FOR EACH HAND, which is a coordination penalty.
• e) If you have an ability of Two-Weapon Combat or Florentine, that negates the one trait penalty for each hand. It does NOT negate the penalty for using your off hand.
• f) You only get ONE extra action for using both hands, at the end of the round. Thus, if you’re using enough Celerity to get an extra action, you get your basic action with your on hand, your Celerity action, and your action for your off hand. You do NOT get an extra Celerity action for each hand.

So, if you are going to use two guns at once, or two knives at once, or a knife in one hand and a gun in the other or…(you get the idea), you effectively have two actions. For your on hand, it is the regular one trait to initiate a challenge plus the coordination penalty trait in (d), for a total of two traits. For your off hand, it is one trait to initiate a challenge, the two trait penalty for using your off-hand (b) and the coordination penalty one trait (d) for a total of four traits. That totals six traits for the round.

If you have Ambidextrous, your on hand costs the same, the trait to initiate the challenge and coordination penalty (d), total two. Your off hand loses the two trait penalty (b), but retains the coordination penalty (d), plus the regular trait to initiate a challenge for a total of two. Total for the round: four traits

Florentine and Two-Weapon but not Ambidextrous: The on hand costs one trait to initiate a challenge but no coordination penalty (d) for a total of one. The off hand costs one trait to initiate plus the off hand penalty two traits (b), but no coordination penalty (d) for a total of three. Total for the round: four traits.

Florentine and Ambidextrous: The on hand costs one trait to initiate a challenge. There is no coordination penalty (d). Total for that hand: one. The off hand costs one trait to initiate a challenge; there is no off hand penalty (b) or coordination penalty (d). Total for the off hand: one. Total for the round: Two traits.
