I did add tribes.
I updated it so tribes will attack and destroy anything on claimed land except walls or anything that blocks, like a tree. So for now, if walled, you are ok. I still need to add an alert or history message so you know a tribe visited, maybe.
Not sure I will code it to add them back in if they get removed by players. The players are subdue-ing the land so they shouldn't spawn back. Or they should not spawn back near a town. So build enough towns and it could eliminate them completely... when town building comes some day. For now I am just manually adding them.
One defense idea I have for magic is Ward spells you can cast on land that will keep things off.
Damage type I think is the main factor that affects this. If walls have 1000+ (or infinite) armor on the normal damages (thrust, bash, cut, etc) then nothing gonna affect them except special damages like "MegaBash" or what ever.
But... ultimately, no ones land is ever 100% safe. I don't want it to be too extreme but from the start I decided this isn't your normal, safe, online game where players are spoon fed baby food and coddled (for their $$$) and told everything is gonna be alright... it ain't! The previous humans that lived there centuries ago were driven out or killed. I plan to give you (and me) a real freakin' challenge to stay there. Actually, I just want to put in a lot of ways to kill you all... hey, at least I am honest
