Attack: All Units in this Hero’s Region move up to to Battle the player. The Enemy can move in any direction and the compass is ignored, except for breaking a tie between two eligible targets of equal Natural Strength (it doesn't know what bonuses you have). However, they will only attack if the Natural Strength of the player's army is less than or equal to the Natural Strength of the Enemy Hero's army. If there are multiple player armies within range, the Enemy will attack the weakest one. Ties for choosing the weakest army are broken by referring to the movement compass, and going clockwise, then choosing the first army it can reach. The Enemy also gains for starting a Battle.
This action will fail if there are no player armies within of the Hero, or the armies are stronger than it.
