Aika SEA Castle Siege Guide

Aika SEA Castle Siege Guide by hatak3kakashi

Castle Siege is a PvP (player versus player) feature unique to Aika where the guilds and guild alliances within a nation compete in a bloody campaign to secure the Lakian Fortress — the ultimate national seat of power. Every week, all five nations will each be host to a potential military revolution, where the Lord Marshal and his ruling regime must defend the Fortress against an onslaught of would-be usurper guilds and guild alliances.

A guild which aspires to reign may form an alliance with up to three other guilds and perfect a strategy for takeover. However, since only one of up to four alliances (aside from the incumbent guild or guild alliance) may rule over the nation, each alliance must also fend off other rivals for the throne. The considerable rewards of attaining ruler status through Castle Siege are not easily won, but ambitious guilds led by formidable guildmasters won’t ignore the opportunity to acquire power of this scale. The Lord Marshal of every nation controls taxation, relic upgrades, international military alliances, allocation of defensive resources, and more.

Every week, guilds and guild alliances may apply via the Castle Siege Administrator in Regenshein during a specific time window to participate in that week’s Castle Siege. There is room for up to 16 guilds to compete, including guilds in alliances. The regime in power is automatically entered into the battle. The final list of guilds and guild alliances is announced the day before the Castle Siege. Guilds on the offensive side are assigned to one of four starting points on the outside of the Fortress (A through D in the graphic below), while the Lord Marshal’s guild or guild alliance takes the fifth point (E). In order to achieve victory, a guild or guild alliance must break down one of the gates to gain entry into the castle, tag three out of five of its protective orbs to break the shield over the Marshal’s Flag, and then keep other attacking guilds and the defending regime busy while its guildmaster takes the flag from the central platform. This must be accomplished within the Castle Siege time limit, which is one hour.

Once a guildmaster has successfully acquired the flag, the Castle Siege is over and that guildmaster’s guild or guild alliance has won supreme control over the nation for the week. If the battle was won by a guild alliance, the guildmaster of the leading guild in the alliance becomes Lord Marshal and the other alliance guildmasters become Archons. The Archons assist the Lord Marshal in ruling the nation, and they and their guild members receive status boosts as well. If none of the attacking guilds or guild alliances accomplishes this goal, the incumbent regime has retained the right to continue its dominion over the nation.
