MMORPG.com Age of Conan Correspondent Garrett Perkins writes this guide to the siege system for first-time players of Funcom's "M" rated MMO.
The border kingdoms of Hyboria are where the best of the best duke it out in an epic battle of wits and strength to find out who has the right to rule over one of the few battle keeps that are available on each server. Siege is the apex of PvP in Age of Conan in which there is a defending and attacking guild fighting during a set time frame (set by the defending guild) over a battle keep. These battle keeps offer up extreme PvP and PvE stat bonuses along with the bragging rights that come with owning one of the selective structures. This makes the battles to claim and defend those keeps extremely brutal, and sometimes even personal. Knowledge can always change the tide of battle, so I put up this little guide on the basics of how Sieges work in AoC so that rookie warriors won't be caught clueless on this merciless battlefield.
Getting a BK / applying for siege:
First off before you can even try and apply to siege your guild must:
1. Have a T3 city keep (you do not need T3 buildings though)
2. Have the minimum number of guild PvP points* to bid on the attacking siege spot
*Guild PvP points are gained every time someone in your guild completes a PvP mini game or kills a player of an enemy guild (that you have just declared siege on) your guild master can then use these points to bid against other guilds attempting to siege the same keep as you.
