This plugin changes how the Attack Count option works for weapons that use the custom parameter 'brave'. Basically, an unit with a "brave" weapon will only attack once if it is the defending unit.
For example, a "Brave Sword" with an attack count of 2 will attack twice if the unit is the attacker, and it will attack once if the unit is the defender.
To make a weapon use this restriction, you need to assign it the custom paramete {brave: true}.
