While exploring the Land of Shadow in Elden Ring Shadow of the Erdtree, you'll likely stumble upon the back of Shadow Keep which is filled with water. Here's how to drain all the water there.
How to drain the water at Shadow Keep in Elden Ring Shadow of the Erdtree DLC
To drain the water at Shadow Keep, you'll have to start at the back of it, at the Church District. From the Church District Site of Grace head to the church building roof on the other side by jumping over the roofs and walls. After you do that, head to the furthest end of the church building roof you just arrived on.
You'll see brick structures connecting the pillars there. Jump on them and move upward. You'll land on a broken roof with a big hole in the middle.
Carefully land down on the the middle of supporting structure and jump down to the lowest floor of the building. You'll see a doorway at the front of you. A Fire Knight will also be roaming so be on guard. A few steps from the doorway is another doorway at the left leading outside. This is the doorway you should be taking.
You'll notice there is a pathway to another side of the tower. Follow where the pathway takes you to the left. There should be a few bats but there is easy to take care of. At the end, you'll find a ladder which you'll have to climb up. You'll see the water-draining lever at the front. Turning the lever will drain the water in Shadow Keep and will let you explore what is below.
