You place an invisible sensor on one cartridge or musketball that you touch. When that piece of ammunition is fired, you gain a memory of what the sensor saw along the path of the bullet, to a maximum distance of 400 feet. You can see anything along the path of the bullet clearly within 60 feet; anything beyond that is blurry blobs of color and light. What you see is frozen in time at the instant the bullet passed by, but you can examine any part of the image as if you were where the bullet was. The spell does not grant you any special form of sight or vision. You can study this image for up to 10 minutes as long as you can maintain concentration, and then it fades; you still remember what you saw, but you can no longer see or study any new part of it. If the piece of ammunition isn’t fired within 8 hours, the magic dissipates and the spell is wasted.
