Mounted Attacks

You and your mount fight as a unit. Consequently, you share a multiple attack penalty. For example, if you Strike and then Command an Animal to have your mount Strike, your mount's attack takes a –5 multiple attack penalty. You occupy every square of your mount's space for the purpose of making attacks. If you were a Medium creature on a Large mount, you could attack a creature on one side of your mount, then attack on the opposite side. On a Medium or smaller mount, use the normal reach of an attack. On a Large or Huge mount, you can attack any square adjacent to the mount if you have 5- or 10-foot reach, or any square within 10 feet of the mount (including diagonally) if you have 15-foot reach. Use the adjusted reach for determining flanking and other rules that depend on reach.
