If an attack by a monster or weapon with Knockback inflicts at least 1 damage (before applying armor), the attacker may immediately move each affected target figure up to three spaces away from its current location. This is reduced by one space of movement for each space the target occupies beyond the first. The figures must be moved to spaces that do not contain other figures or obstacles that block movement. The figure does not actually move through the intervening spaces. As such, Knockback movement is not blocked by intervening figures or obstacles (though a figure cannot be moved through a closed door or wall).
