Coins of unforgiving Greed

the coins can fire metal objects at incredible speeds using electricity. The "bullets" are coins that has a muzzle velocity of around 1030 m/s (2307.2 mph) and that she can fire her "projectiles" a rate of 8 shots per minute. The projectile It uses are almost always arcade coirefns, but it claims the coins melt from friction with the atmosphere at around 50 meters, limiting the railgun's effective length there. It can replace the coins with a much larger projectile and yields more power and can travel further than an ordinary Railgun. The name somewhat contradicts the details of how an actual railgun functions, though, as she doesn't use "conducting rails" in her ability. although a rail gun is really just two rods using the right hand rule and conducting eletricity to propel a projectile. this however still contradicts as she would be shown needing to use both arms to coil eletricity around them to produce a magnetic force
