When the Animal Attacks - When riding an animal, the animal will fight automatically if it is trained to do so. Every time the animal attacks or defends, the rider must make a roll using their riding ability to stay mounted.
Stopping the Attack - To keep the animal from attacking the rider must make an animal handling success roll every time the animal is attacked, and every round that the animal's attacker is visible. The difficulty of this roll is +2 points against success, or +4 if the animal has taken damage.
Animals that do not Fight - Animals trained to be ridden but not to fight, will not attack if they are being ridden, instead they will try to run unless a successful animal handling roll succeeds. The difficulty of this roll is +3 points against success, or +5 if the animal has taken damage.
Charging Attack - A rider's attack damage is increased by the speed of his steed. See Action/Maneuvering/Speed Damage.
