Well, here is a guide for field war in 4Story, just go through and have a good time in the game!

You may attack players of hostile kingdom. WarUsers are allowed to attack the players from Hostile Kingdoms at any time.
If the user defeats the player from Hostile Kingdom with similar level, will receive certain Fame points whereas if the user defeats the player from Hostile Kingdom with lower level, the user will lose the Fame points.

Within the territory of the user's Kingdom, the user can attack the player from Hostile Kingdom. However, once the player from Hostile Kingdom is attacked, he/she is allowed to fight back.

Within the War District, whether its occupied by own Kingdom or Hostile Kingdom, the preemptive strike against each other is allowed.
