45 day in.
With arrows when they missing, greatsword swing and split, greataxe round swing. It is ok since you can hurt your own people aswell, but the guards should have a limit of friendly fire before they turn against you or other punishing mechanics.
As of right now its highly exploitable. Did a test run, just following a strong castle patrol with a fresh party, in 2 fights they became weak and me full of their mid and late game equipment. And that was even without killing them off. Would make sense if they would take a big bunch of loot after their battles leaving just few spoils to the marauders. Unfortunately that creates a question about loot if I participate fully on their side…
