The Kingdom and the 7 Sieges

About this Mod

Kingdoms and Sieges, a mod that attempts to give players a more authentic feel when it comes to siege warfare. This mod is designed to go in tandem with the Knights and Heraldry mod but is it standalone and doesn't require Knights and Heraldry to be installed.

Kingdoms

Spoiler

The player can create their own kingdom by placing a bell block and then right-clicking it with a banner. This will give you a new item: 'Crown' which will allow you to see how big your claim is and interact with other Kingdom features. You may also use a nametag to rename your kingdom by right-clicking the bell with the nametag.

To add or remove players to your kingdom, have the crown equipped and right-click players with an empty hand.

Only players who are in the kingdom can place and break blocks unless a siege engine is used (more about this below). Mobs will also not spawn inside kingdoms as well.

You can increase your claim by giving your bell emeralds, this will expand the radius of your claim.

Should anyone who isn't a part of your kingdom push siege engines or launch projectiles into your kingdom, this will begin a siege.

Sieges

Spoiler

This mod will essentially try to boil down what usually takes months to years to do into a couple of hours.

Whenever a siege begins, all players involved with the siege will be given the hunger effect to represent the use of resources in a siege and to encourage players to make effective supply chains to keep themselves fed.

Anyone who dies taking part of the siege and respawns are considered out of the fight and whenever they enter a kingdom, they will raise their arms in surrender and cannot kill or be killed for the rest of the siege. And if anyone of the defending kingdom dies, they will lose kingdom wealth and their kingdom claim will reduce in size.

Kingdom mechanics are still in effect, players who aren't part of the kingdom cannot break or place blocks, however, any siege equipment can. This will force players to make heavy use of siege engines and artillery to try and breach any defences that the kingdom has put up. It will also prevent players from just building siege engines, right up against any build defences.

A siege is won when one of these objectives are completed:

  • The defending kingdom's bell is broken. This will abolish and destroy the kingdom's claim.
  • All the attackers have died and been taken out of the fight.
  • Either attacker or defending kingdoms right-click their kingdoms' bells to surrender.

Siege Engines

Spoiler

To make a siege engine, you will need to build one like how you build an iron golem. To find out how to build them, you will need to go out and find manuscripts hidden as loot. You do not need the manuscript to build these, it's just there to show you how to build them.

You can find these manuscripts at pillager outposts, mansions and villages.
