Charge Reactions (Appendix Four - Rule of Siege)
URL Copied!

Troops defending walls can declare normal charge reactions, and can use boiling oil and rocks in a stand & shoot reaction, unless the chargers are using a siege tower. The defenders can, still use normal missile weapons, such as bows, etc, against a charge from a siege tower. The defenders may also choose the Man the Walls! charge reaction.
