Mounted

Penalties suffered to ranged attacks while mounted are halved (-1 if taking a double move, or -2 while running).

You take a -2 penalty when making ranged attacks on a mount making a double move, and -4 when the mount is running.

The penalty you take when using a ranged weapon while mounted is halved: -2 instead of -4 if your mount is taking a double move, and -4 instead of -8 if your mount is running.

A fighter may select Mounted Archery as one of his fighter bonus feats.

Once per round when your mount is hit in combat, you may attempt a Ride check (as a reaction) to negate the hit. The hit is negated if your Ride check result is greater than the opponent's attack roll. (Essentially, the Ride check result becomes the mount's Armor Class if it's higher than the mount's regular AC.)

A fighter may select Mounted Combat as one of his fighter bonus feats.

When you are mounted and use the charge action, you may move and attack as if with a standard charge and then move again (continuing the straight line of the charge). Your total movement for the round can't exceed double your mounted speed. You and your mount do not provoke an attack of opportunity from the opponent that you attack.

A fighter may select Ride-By Attack as one of his fighter bonus feats.

When mounted and using the charge action, you deal double damage with a melee weapon (or triple damage with a lance).

A fighter may select Spirited Charge as one of his fighter bonus feats.

When you attempt to overrun an opponent while mounted, your target may not choose to avoid you. Your mount may make one hoof attack against any target you knock down, gaining the standard +4 bonus on attack rolls against prone targets.

A fighter may select Trample as one of his fighter bonus feats.
