This is an extremely unique suggestion and I can't say I've ever seen a Medieval RP in the slightest, although it seems like a great idea. My complaints arise when say, How will raids be committed without raid guns, How will people respond to PvP with Swords and Bows, and Where are the mods to make this possible. I can understand a King will be throned similar to how Mayors are in RP. Could you also go into more detail on how the Execution Sentence works? It'll likely be a nightmare for the logs, regarding kos. It's a very flawed idea, but an extremely unique one to boot. +1 for the unique idea.
Well so I have 2 dumb ideas to replace raid guns, powder in a bottle/canons, termite bottles/ flame bottles, the powder one directly does it and flames/termites over short time destroys it.
maybe there will be magic, also maybe mod in so alt attacks do something special, it is weird.
Execution is when a king makes it so a certain person/people are arrest able, put in dungeon immediately and then executed and blacklisted from all noble rankings or army.
