Add Field battles that:
-Are started by placing a sign with name of town you are attacking and banner next to it in wilderness
-Can not be started more than 2000 blocks away from enemy town
-Can not be started less than 500 blocks (or 1000) away from allied town
-Can not be started within 500 blocks of last site on which field battle already happened recently (7 days)
-Drop double points from kills
-Last 1 day
-Reward 20% point bonus on next siege on specified town , which stacks up to 3 times on attacker victory
-Reward 1 day of immunity on Defender Victory
-Dont award plunder
-Each Nation can only start 1 offensive field battle at once (you can start a field battle even if you are attacked first, to prevent anyone from basically spamming battles in order to make the other side unable to start them, also multiple nations can start a battle of their own against the same nation, basically an attack from multiple fronts)
-Cannot be started at the same time when siege is started on the specified town(just to avoid confusion, not like its a good idea anyway)
They are meant as capture the flag in wilderness, with neither team having the advantage of their defenses
and should be used as means to go to war and build up advantage battle after battle before finally deciding to do the siege, which should be seen as
"The Boss Fight" of a war, meaning, wars could be fought by doing tens of field battles and only a few sieges.
this could also become a site of movecraft vs movecraft battles, because, there is no real reasont to ever fight movecraft vs movecraft if one side always has walls.
