---Sieges should involve spawning an Encampment near your Village, that periodically upgrades, spawns patrols and siege parties, more Bandit Camps and launches artillery against your buildings. Finally, launching an all-out assault upon you before vanishing.
-First, like Reclaimation Parties, an assembled host will leave the Brigand-HQ factoring in your Tier and weapons research, villager count, building count, Player count, and largely player Combat Attributes/Equipment, spawn between 12-42 elite Brigands with a General that marches till they reach outside your regions border. From there, they'll instantly spawn a large Encampment housing a minimum 24 Bandits, maximum 64 - of various quality relative again to your assets.
If you don't stop the initial Siege Host, the Encampment it spawns is procedurally massive, with dozens of tents, palisades, livestock, etc. Here are the phases and events that occur:
---1. A Supply-Line party is generated twice daily from Brigand-HQ, morning and evening, upon Siege Camp spawn, spawning several ox-carts and 2-3 dozen Brigands that march to their Siege-Camp. When it arrives at the camps Banner, it vanishes, in five minutes upgrading the camp one level up of several and replenishing a large percentage of the camps capacity. Defeating these entirely or killing the cart animals will send the Brigands back to HQ once they de-aggro, stopping the Supply event.
---2. Siege Camps after receiving two Supply events will upgrade in a five minute timer:
Lvl-2: Spikes around the camp with several hunting towers behind them, stationed with 2-3 archers in each. The camp troop base minimum increases by 20%. Brigand Patrols (3-5) will leave the Siege camp every night, purposely going around the borders of the Player's region.
