Minecolonies: War N Taxes Addon

Colonies earn tax revenue that can be configured, and the rates for building upgrades can be set per MineColonies building. Maintenance costs are deducted automatically from building income, so the balance of the colony's tax revenue depends on the settings chosen. A configurable revenue cap stops taxes from accumulating once the maximum is reached.

War mechanics let players raid colonies and claim them, and taxes can be collected from colonies taken in a raid. Vassalization lets a colony take a percentage of another colony's earnings. Citizens of a raided colony can turn into a militia that tries to fend off raiders. Duel team battle arenas can be set up for PvP without changing gameplay progression. Colonies left without an owner or officer for a configurable period, two weeks by default, become abandoned and can be claimed by eligible players with a command that starts a five-minute raid. Citizens of a claimed colony become hostile militia with resistance effects.

The add-on requires Minecolonies. It works with SDMShop for currency, and the author recommends pairing it with FTBTeams and a recruit mod for villagers. Setting SDMShopConversion to false in the config allows another currency mod to be used. A set of war admin commands is available.
