Something knocks the character to the floor, either toppling her with a powerful blow to the chest or taking one of her legs out from under her.
Effect: The character is knocked off her feet. If she hasn’t already acted this turn, she loses her action. Once she’s on the ground, a character is considered prone. The character can still apply Defence against incoming attacks, and can attempt to attack from the ground at a –2 penalty.
Causing the Tilt: Some weapons list “Knockdown” as a special effect of a damaging hit. Otherwise, a melee weapon with a damage modifier of +2 or greater, or a firearm with a damage modifier of +3 or more can be used to knock a character down with the force of the blow. Alternatively, a melee weapon or unarmed attack can knock an opponent down with a targeted attack against the legs (–2 modifier). The attacker declares that he wants to knock his opponent down and halves the total damage done (rounding down). On a successful attack, the target is knocked down.
Ending the Tilt: The easiest way to end this Tilt is to stand up, which takes an action. A character affected by this Tilt who hasn’t yet acted can make a Dexterity + Athletics roll, minus any weapon modifier, instead of her normal action. If successful, she avoids the effects of this Tilt altogether. On a failure, she falls over and the Tilt applies as normal.
