Hmmm, as we all know, wars are one of the many many faults in the Roleplaying system - right now, they are impossible.
Step One.
The attacking kingdom lands on the shores of the Defending kingdom.
They are then allowed 30 minutes to build from stone fortifications and such (with supplies they brought with them, obviously) a fort of whatever shape and size they wish/are capable of. If the fort does not join up completely around the edges with at least 1 fortification, the attacking kingdom is disqualified and the war will have to happen at another time. Also, if they have not completed the fort within the 30 minutes allowed, they will be DQed.
During this time, the defending kingdom is not allowed to go near them
Once the fort is finished, the attacking kingdom is allowed 10 minutes to organise it's troops inside the fort. (kicking out those that disobey XD). Then step two is initiated.
Step Two
This is the Defender's time to attack. Once the 10 minutes are up, regardless of whether the attackers are ready or not, the Defenders are allowed to lay siege upon the fort.
NO MAGIC IS ALLOWED HERE AT ANY POINT
If earth to dust is used, the member who cast it will be removed from the kingdom immediately, without question (he may be allowed back in after the war, or not, depending on that particular kingdom's laws).
-------------------------------------------
If Earth to Dust is cast at any point during step two, the defending kingdom is Disqualified. Step one must be repeated, and if the Defending kingdom is DQed a second time during step two, they lose the whole war right there and then.
-------------------------------------------
Anyway, back to the point. During Step Two, the defending kingdom's objective is to punch a hole 6 fortifications wide in the fort. This breach is only accepted once there is a clear passage from the inside to the outside of the fort.
The objective of the attacking kingdom here is to defend their fort. They are allowed to shoot arrows over the fortifications (as is the defending kingdom) and they are also allowed to "repair" their wall by adding new fortifications to the wall. So, the attackers could make the wall look like this from an aerial view:
--------------------- (note, the ..... represents a gap)
------.........--------
But the defenders could repair the wall so that it looks like this:
...........----------
-------------------------------
----------.........--------------
-The wall is still classed as a wall two fortifications thick-
IF THE WALL IS COMPLETELY BREACHED, AND A MEMBER OF THE OPPOSING KINGDOM MANAGES TO GET INTO THE FORT, THE FIGHTING STOPS IMMEDIATELY!
Step Three - The Battle
Once the fort is breached, the battle here ends and the two kingdoms both move to opposite ends of a predetermined battlefield which both kingdom leaders negotiate and agree upon.
Here, twenty minutes are allowed for both kingdoms to prepare for the following battle, and for any kingdom members who fell at the fort to get back to the battle scene (having been healed and patched up by priests, of course

).
Once the twenty minutes are up, the two opposing sides must charge at each other and fight. This is the only stage in which magic is allowed.
The last Kingdom standing wins

Final Note:I know that this war system CANNOT work right now, due to the major issues in Player VS Player fighting. But still, it's a start!
Tell me what you think, people!
