Camp entranchments, sir.
When finding an entranchment, I saw no use except resting and defending in it. So, when finding one, the easiest way to implement is to make that when you encounter an entranchment, you can have a option menu popping out, just like encountering witches and "dying men". With two options: search or leave.
Clicking on the search option may give you:
- Random amount of gold and "rare" stuff
- Booby traps, which automatically wounds or kills a random amount of men in your group (and the player)
- An actual scene with an entranchment, fighting a random amount of bandits (maybe skeletons?) along with a limited amount of your men, just like bandit camps. after you kill them all, you get your random stuff. Or, failing, you are wounded and unable to move for some time.
Clicking the leave button may give you:
- Leaving (duh)
- Booby traps and leaving
- Failing to leave, fighting the guards (bandits)
Or, apart from the camps, this can be another random encounter with a option menu. You encounter a strange place, there may be something useful over here bla bla... What to do?
This can be the easiest one sir, and can be really easy for you, considering all the awesome stuff you did.
To make this more like a hunt, again, just like the bandit camp missions, lords can give this as a quest, maybe also tavern keepers, farmers, travelers, there is a strange place around here with some stuff hidden in it bla bla you can find and get these bla bla... It can also may or may not appear on the map this way, a completely random encounter or a place already marked.
but, if you have time and the skill, you can create a dungeon scene with bandits inside it, fighting your way in, getting the random rewards from a chest, and getting out. This can be hard and demanding for you, but can be an awesome addition.
