​The Siege Camps are marked on your map in Western Solstice. Cultists will periodically attack with giant Soul Reapers. You and other players need to defeat the waves of enemies, destroy the reaper, and then take down one of the generals that spawn. The format of these world events isn’t unlike other world events like Dolmans and Geysers.

 

But siege camps won’t be the only areas invaded by Daedra. In every non-DLC zone, one delve and one public dungeon will be invaded by the Worm Cult! These locations will be marked with a unique, glowing blue event icon on your map. It’s a great way for base game owners to farm Vitrified Souls and contribute to the war effort.​

 

All of these activities—quests, siege camps, invasions, even just killing Daedra in the world including PvP—will advance your server's progress bar. You can check the progress anytime in the Activity Finder, on the map UI or on the official ESO event page on their website. Once that bar hits 100%, things get spicier.

​

PHASE 2: THE ASSAULT BEGINS 

There is no server downtime for this, so we will flow right into the second phase. The Meridian Lens is complete and now begins its relentless assault on the wall.

 

Your job is the same: keep completing those daily quests to power the lens and protect the camps. But things have gotten more intense. The enemies attacking the siege camps are now more powerful, and a new world boss, the Daedra Ghishzor, a powerful Maldrith, will appear in Western Solstice. You’ll also get access to refreshed repeatable quests! The Supply and Crafting categories each get four and six new quests, respectively, including quests for Alchemy, Provisioning, and Enchanting this time around

Visually, you'll see the camps and the soldiers get significant upgrades as the war effort strengthens. Keep pushing, because the final phase is just around the corner!

​

PHASE 3: BREACH THE WALL

Once your server completes Phase 2, a countdown timer will appear for everyone. This is a built-in delay to let everyone on the server prepare for the final assault. Once that timer hits zero, Phase 3 begins. Note: this phase is exclusively for 2025 Content Pass owners.

 

The Meridian Lens finally breaches the wall, but it doesn't just create a hole—it tears open a rift into a new public instance: the Writhing Fortress.

 

This is it. The climax of the battle. You and your allies will need to enter this instance, fight your way through the Tower Guardians, and destroy the Soul Tower that is sustaining the wall.

 

This is the important part. The Writhing Fortress instance is only available during the event. Once your server clears it for the first time, a permanent hole in the wall will appear, granting access to Eastern Solstice for everyone with the Content Pass. But what about the instance? It will remain open for one week after that first clear. This gives you a seven-day window to complete it yourself. If you manage to clear it in that time, you'll earn the exclusive title, "Wall Breaker." Don't miss out on this!

​

THE LOOT: REWARDS BREAKDOWN

First thing to note, there are NO event tickets. Instead, you’ll just be earning Writhing Reward Coffers.

 

You can earn up to three Glorious coffers per day—one for the first completion of a siege camp defense quest, a crafting quest and either a supply quest or Vitrified Souls quest each day. Clarification: the supply and souls quests will only award one Glorious coffer for doing one or the other, not one each both. After that, you'll get standard purple coffers for additional dailies and for defeating generals and the new world boss. These coffers can contain a ton of brand-new items. 

 

Vitrified Souls quest coffers:

• A gear set item from Western Solstice, with a chance of a second

• A chance of a style item for the Fellowship of Stirk crafting style (Glorious coffers guarantee one)

• A low chance of at one of the following with a guarantee in Glorious coffers:

  • Wormwrithe armor outfit style page

  • Wormwrithe weapon outfit style page

  • Wormwrithe Haj Mota pet fragment

  • Caltrops, Bone Skill Style fragment (starting in Phase 2)

• A chance for a sellable treasure of varying value (Glorious coffers guarantee one)

  • This reward has a very low chance to be replaced with the Coldharbour Surreal Estate if you do not already own it, or with a sellable treasure of exceptional value if you do

 

Siege Camp quest coffers:

• A gear set item from Western Solstice, with a chance of a second

• A chance of a style item for the Fellowship of Stirk crafting style (Glorious coffers guarantee one)

• A low chance of at one of the following with a guarantee in Glorious coffers:

  • Wormwrithe armor outfit style page

  • Wormwrithe weapon outfit style page (starting in Phase 2)

  • Wormwrithe Haj Mota pet fragment

  • Caltrops, Bone Skill Style fragment (starting in Phase 2)

• A chance for a sellable treasure of varying value (Glorious coffers guarantee one)

  • This reward has a very low chance to be replaced with the Coldharbour Surreal Estate if you do not already own it, or with a sellable treasure of exceptional value if you do

 

Crafting quest coffers:

• A set item from the Invaded Delve or Public Dungeon where the boss was found, if applicable

• A low chance of a Writhing Wall-themed furnishing

​

Incursion chests at Siege Camp (daily quest not required):

• A gear set item from Solstice

• Gold

• A chance at a style item for the Fellowship of Stirk crafting style

• A chance at a Fellowship of Stirk motif page, or in rare cases, the entire book

• Sellable treasures

• A low chance of at one of the following:

  • Wormwrithe armor outfit style page

  • Wormwrithe weapon outfit style page

  • Wormwrithe Haj Mota pet fragment

  • Caltrops, Bone Skill Style fragment (starting in Phase 2)

​

Collectibles and items awarded through the Battle for the Writhing Wall event will remain in game even after your server has completed the event. These rewards, apart from the “Wall Breaker” title, will be sometimes awarded through the Siege Camp daily quests in addition to the possible rewards for Siege Camps already listed above.

​

During the event there will also be a new Golden Pursuit running. The tasks for this campaign complement the event’s activities and challenges, so you’ll likely speed through those tasks if you’re participating in the event. The big rewards include the Coldharbour Dremnaken Runt pet and the Wormwrithe Bear-Lizard mount.

FINAL TIPS & POST-EVENT INFO 

A few final things to keep in mind:

• You do not need to complete the main questline in Western Solstice to participate in the event. Everyone can jump in—but it will give some good context to the purpose of the event.

• After the event is over, the Siege Camp dailies will still be available, as well as the world events, but they will happen less frequently, and the event rewards will have a much lower drop rate. The invasion sites will return to normal, and all bad guys will turn back into their regular bad selves.

• The state of the wall is per-character after the event ends. If you complete the questline on that character, it's gone. If you haven't, you'll see a damaged version of the wall until you complete the quest on that character.

• Antiquity leads normally dropped from specific bosses in Delves and Public Dungeons that become invasion sites will drop from event bosses in that Delve or Public Dungeon for event’s duration.

• To earn the title, you must complete the Writhing Fortress during Phase 3 of the event. This reward can be earned only by players who own the 2025 Content Pass.

• Once the event kicks off Prince Azah (found in the Sunport Rampart Camp) will have a new zone story quest, “Crossing the Wall,” for players that have completed the first part of the zone quest line. This quest will continue the story into Part 2.

• Crafting dailies can be done right on site which will save you a ton of time.

• Don't underestimate the power of friendship... being cheap means using your friends to open up wayshrines and areas with supplies. Use the Beam Me Up addon or port to a friend or guild member to travel quickly for free.

• PD and Delves invasions will have a worm cult general ready to push you back and they can be a little spicier than normal PD and delves bosses so having a friend or a companion might be a good idea.

• When fulfilling your quest for vitrified souls it will show you a specific location on the map but you can go anywhere and get credit.

• When farming supplies, kill a ton of enemies before looting if you want to get extra supplies to hold on to for the next time you complete that specific quest. It’ll save you some time if you’re in a hurry.
