The Talismanic Arrow's main buff is related to how much Karma you gain for everything you do in Rise of the Ronin. Because Karma is cashed in for skill points, it goes without saying that you will want to build up as much as possible. Early versions will give you low percentage increases, but when you consider how much Karam you get all the time, it adds up fast. The extra perks that come with it are less important but may end up helping your build as well.
