Tower 4 is directly east of Tower 3. As soon as you enter the Tower, Guardian is there to greet you. He is impressed that Ark has made it this far, and immediately sends 3 wizards after him. The wizards are easily destroyed. In Tower 4, you will be learning how to walk across ropes. To walk across a rope, just align Ark up with the rope and walk normally across. You don't have to press any special buttons; just walk.
The first floor doesn't have too much on it. You have to choose whether you want to walk across the rope to the left side or the right side. Either way, you still end up in the same place; at the top of the room. But it looks like the only way down is to jump, which is exactly what Ark must do.
Ark lands in the Basement1, which has two parts to it; a lower level and a higher level that you can't get to by any staircase from the lower level. In the lower level there are some wizards and a wall gardner, so watch out for those. There are 4 holes that you can jump down that will lead you into the Basement2, one in each corner of the room.



The red location, orange location, and the purple location all lead to the exact same spot. The blue location leads a different way (and the correct way through the tower). So there are actually only two paths you can take.
First the 3 dead ends.....
Each of the other holes (the upper right, upper left, and lower left) drop to a location in the floor below Basement1. This we would call Basment2. The only enemies here are firewheels and orange pill-bugs, except for the hole in the upper left of Basement 1, which lands in the orange location and right next to a wall gardner. No matter which one of the spots you land in, the only exit from this area of Basement 2 is the left staircase in the upper portion of the room.



Going up the stairs takes you to a small room on the first floor. All you can do is continue up the next flight of stairs.
Ark emerges onto the right side of the second floor of the Tower, where there are two ropes spanning the large gap in the floor. If you fall off the rope, you'll land on the first floor. At that point if you wanted to get back to the second floor, you would have to fall down into Basement 2 and climb back up the stairs.
The bottom rope strings across the gap but eventually stops at a platform containing a MagiRock before the rope continues over to the left side of the room. The upper rope goes right across to the left side of the room. On the upper left corner of the room there are two treasure chests. One contains a MBulb and the other has a Life Potion. And this is where the dead end is. From here the only way is back down. You can either go back across the rope and climb down the stairs to Basment1, or you can fall from the second floor to the first floor, and then fall to Basment1. It's up to you.
Now that you're back in Basment1, this time Ark will take the lower right hole to fall down through. From here, you land on the right hand side of Basment 2, which is a completely separate area then the rest of Basement2. Head toward the staircase that is in front of you.
And again you'll end up back on the first floor, but in another area that just has a staircase and nothing else. Continue up the stairs. This time you'll be on the second floor, but there will be a large hole that you can jump down and also a staircase. Unless you really want to, don't jump down the hole. It will take you back to the first floor, and you will have to fall back down to Basment2 to return to where you are now. Just continue on up the staircase.
Now Ark has reached the third floor finally. Follow the path until it branches off north. Go into the room and open the treasure box. You'll receive the Crystal Thread. Leave the room and follow the path until you come across two ropes. You can take either one, but the top rope goes across a platform with a quickly spinning firewheel that could potentially knock you off and you'd have to climb the tower all over again, so you may want to take the lower rope. Besides, the lower rope is closer to the MagiRock that is waiting in the lower right corner of the room. From the right side of the room, travel north until you come across a third rope. Walk across that and you'll find the control room.
The Guardian's voice will mention that he has created a show for you to watch and he transports you away into another room. Suddenly a train of Huballs come flying at Ark, but the last huball is gold while the others are blue. Hit the gold Huball to break it loose from the train and either destroy it, or hit it off the platform.



In the middle of the night you wake up. Go visit Elle and she will still be working on Ark's cloak even though she should be alseep. She tells him that she's worried that he will be leaving soon and will be going far away. Then she tells you to go back to bed. In the morning, revisit Elle and she will give you the ElleCape. You will need it to enter the fifth Tower.
