Lake tower is going to be easy or hard, depending on how well you deal with Poe’s. They have the magic wand weapons and can do quite a bit of damage. You will need to be quick with your bow to be able to deal with them. They are in high numbers in the area, making it difficult to get to the tower without interacting with them at some stage or other. You may be able to put your climbing skills to the test if you want to try and get around the other side of the tower. It is up to you.
