Your Alliance can try to take an enemy keep at any time in Elder Scrolls Online. To take a keep and convert it to your Alliance, enough allies must first break the outer wall, then the inner wall, and then finally take each of the two flags inside the keep. Allies standing on the flags will all help to take that flag and convert it to your Alliance. Find out more about taking keeps in Cyrodil for ESO account holders in the article below!
Expanding your Alliance for ESO Account Holders
This might sound simple but it can be a long and complex process. It is often wise to take at least one resource of the keep before attacking as this will give you an area to fall back to if things get tough. You can use the support of friendly NPCs at that resource to defend your allies when you do have to fall back. Taking a resource may alert the enemy of your presence, however, and might result in quick reinforcements of defenders.
Taking Down the Outer Walls for ESO Account Holders
The outer wall is strong and large, as expected of outer walls. Siege weapons will be required to break it down, so you should at least have a few on your Elder Scrolls Online account. Stone Trebuchets and Ballistae are the best at damaging a keep wall. If your Alliance gathers enough TESO account holders to operate the siege weapons, then the wall can come down pretty easily within a couple of minutes. Note that the defenders of the keep will try to destroy your siege weapons and kill your allies in retaliation. They might also use siege weapons like Fire Ballistae and Boiling Oil to defend the hole in their wall. Make sure you deal with them as well.
In the event that your Alliance might decide that it already has enough players to directly attack the front door, remember that this may not a good idea as guards are constantly watching the front door. You can tilt the situation in your favor if you have lot of allies, though. With enough troops, you can use Rams to quickly bash down the front doors, and this may result in a quicker entrance. Once the wall is down, your Alliance can pour in and start to take down the inner wall.
Breaching the Inner Walls for ESO Account Holders
There are NPCs inside the keep wall. These NPCs are of Veteran Rank 12, so they can actually be a pain. Enemy players are even worse and they can be sneaking about ready to attack your allies on siege weapons. The inner wall is similar to the outer wall and will eventually fall if enough siege weapons are operating and you are not killed by the guards or by defenders. There is also a front door which can be opened through Rams but it is highly-likely that it’s defended well, and enemy players can easily rain down Boiling Oil on to your allies while they are trying to break open the door.
This is why careful planning is needed before infiltrating another keep. You may fail a few times on your TESO account, but you’ll eventually get the hang of it. All you need is a laid-out strategy, and allies who are willing to go along your tactics!
