In the 11th siege war held on August 30, both alliances experienced a pattern of losing one castle while gaining another. On the Astair server, The K Alliance achieved a 3-castle sweep, whereas on the Valakas server, the No Tongsoo Alliance secured all three castles. Meanwhile, on another major battlefield, the Pa'agrio server, The K Alliance went on the offensive more aggressively, leading to continuous shifts between offense and defense.

On Astair, although the No Tongsoo Alliance still demonstrated overwhelming numbers even on enemy turf with the participation of the so-called Bottoldan, the difference in individual combat power and the counter-strategy against their repeatedly exposed tactics ultimately allowed The K Alliance to recapture the Orc Fortress. The No Tongsoo Alliance continually targeted Windawood Castle searching for openings, but they only managed to slightly push back the barricade line.

On Pa'agrio, The K Alliance appears to be gradually building up its combat strength step-by-step. At the time of the server transfer, The K Alliance was heavily pushed back, barely securing the Orc Fortress. However, with each passing siege, they elevated themselves to taking Windawood Castle, successfully defended it, and this week went beyond defending to launch continuous attacks on other castles, creating a much fiercer struggle. Nonetheless, with the No Tongsoo Alliance's forces proving equally formidable, neither team managed to produce results on offense.

On Valakas, the No Tongsoo Alliance successfully suppressed the Anti-King resistance led by the Valla Alliance (The K Alliance). Having already suffered a reduction in size last week, internal strife led their former ally, the Empire Bloodpledge, to defect to the No Tongsoo Alliance. This widened the power gap even further, allowing the No Tongsoo Alliance to easily achieve a 3-castle sweep.

Demonstrating their ability to counter the enemy's strategies and tactics, The K Alliance successfully reclaimed a 3-castle sweep on the Astair server.

On the Astair server, even before the siege officially began, both alliances engaged in a tense psychological battle around the outer gates. Windawood Castle was chosen as the main battlefield. The strategy was to surround the main gate with Bottoldan Elves to wage a war of attrition, while committing the main force to the east gate in an attempt to breach Windawood Castle. Meanwhile, Kent Castle remained quiet.

However, this attack yielded little result. Despite battering the castle gate for tens of minutes into the mid-game of the siege war, the No Tongsoo Alliance failed to break the defensive formation. Furthermore, seeing that the assault was concentrated on Windawood Castle, The K Alliance briefly opened a gap to reinforce the castle interior with troops from the Dangyeol Bloodpledge, making a breakthrough even more difficult for the No Tongsoo Alliance.

Ultimately left with only a minor result—picking off a player or two at the barricade line—the No Tongsoo Alliance shifted their target to the Orc Fortress around the 40-minute mark. Although The K Alliance had dispatched a small force beforehand to capture the Orc Fortress, the sudden influx of the No Tongsoo Alliance's full army quickly flipped ownership of the castle, triggering yet another round of battle for the Orc Fortress.

However, with each weekly siege, the speed at which the No Tongsoo Alliance's defense line at the Orc Fortress was breached grew faster. Alternating attacks between the north and main gates by The K Alliance eventually opened an entry path. Although the No Tongsoo Alliance mobilized multiple Bloodpledges such as Hookteam and Astair Top in an effort to swap castle ownership, the Dangyeol A Bloodpledge of The K Alliance succeeded in engraving the Orc Fortress with just 2 to 3 minutes remaining in the siege. The K Alliance then successfully defended by changing the castle lord 1 minute before the end, recapturing the Orc Fortress two weeks after losing it on the 16th. In the meantime, the No Tongsoo Alliance targeted openings at Windawood Castle, where defenses had weakened, but failed to break through.

On the Pa'agrio server, the dynamic between the two teams is growing increasingly tense. Ever since The K Alliance claimed Windawood Castle, the siege on Pa'agrio had been a contest between the No Tongsoo Alliance trying to reclaim it and The K Alliance fending them off. However, with The K Alliance establishing a solid defense and launching attacks on other castles, the situation on Pa'agrio is spiraling into an unpredictable chaotic brawl.

Signs of a chaotic brawl appeared from the very start of the siege. Facing the No Tongsoo Alliance, who were preparing to assault Windawood Castle just as they did last week, The K Alliance used an interception unit to cut off the enemy's midsection before immediately launching an attack on Kent Castle. Perhaps because it had been so long since The K Alliance had mounted a full-scale offensive, the ill-prepared Kent Castle saw its east gate quickly breached, allowing The K Alliance troops to advance deep inside.

This assault did not result in a change of castle ownership, as the No Tongsoo Alliance forces attacking Windawood Castle immediately retreated to defend Kent Castle, thwarting the push. From that moment on, however, forces from both alliances traded offensive and defensive roles turn by turn, almost like a round of slap fighting.

Thus, large-scale clashes unfolded alternating between Windawood and Kent. As if proving that both teams' forces are now evenly matched, neither castle allowed the enemy to breach deep. With The K Alliance securing Windawood and the No Tongsoo Alliance solidifying Kent, The K Alliance alternated attacks on the Orc Fortress and Kent Castle, while the No Tongsoo Alliance balanced defense with repeated raids on Windawood Castle. However, none of these actions resulted in an engraving before the siege came to an end.

In terms of overall dynamics, the Pa'agrio server is currently witnessing the most intense psychological tug-of-war between the two alliances. Arguments contend that, no matter what, the No Tongsoo Alliance holds two castles, while counterarguments claim that momentum belongs to The K Alliance, which has expanded its targets beyond Windawood to other castles. With the balances on Astair and Valakas heavily tilted to one side, the outcome of the battle on Pa'agrio is expected to exert an even greater influence on the overall power structure.

On Valakas, the Anti-King faction Valla Alliance (The K Alliance), which saw its forces shrink last week, suffered internal dissension. Internal conflict led the ally Empire Bloodpledge to defect to the No Tongsoo Alliance, completely tilting the balance of power.

Judging that it would be difficult to hold Windawood Castle captured last week, The K Alliance decided to launch an attack on Kent Castle right as the siege began. The strategy worked: Kent Castle's defensive line was breached in just 2 minutes, and the Tower of Insignia collapsed quickly, changing Kent Castle's lord to The K Alliance.

However, this was as far as the heavily diminished K Alliance could achieve. Meanwhile, the No Tongsoo Alliance easily succeeded in engraving Windawood Castle, and under the onslaught of swarming enemy troops, Kent Castle's Tower of Insignia collapsed again just 2 minutes after the ownership change.

From then on, the outnumbered Anti-King rebels fought a desperate battle, but the disparity in troop numbers was simply overwhelming. Although The K Alliance fought on by focus-firing targets one by one in front of the castle gate, for every single No Tongsoo Alliance member they took down, three of their own were pushed back.

In an effort to overcome the numerical disadvantage, The K Alliance continued fighting by shifting their attack targets from Kent to Windawood, then from the Orc Fortress back to Kent. However, as combat dragged on, the battlefield was quickly dominated by No Tongsoo Alliance forces.

With 10 minutes remaining in the siege, The K Alliance managed to push as far as the Tower of Insignia at the Orc Fortress, but failed to complete the engraving. Ultimately, they rallied all their forces for a final assault on Windawood Castle; while a portion of their troops breached the main gate and gained entry, the main force was unable to follow through, resulting in a 3-castle sweep for the No Tongsoo Alliance.
