Use Arresto Momentum to Freeze the Pendulum In Front of Unicorn Symbol

To open the locked doors at the Clock Tower, you need to freeze the swinging pendulum with Arresto Momentum right in front of the symbol on the wooden beam that matches the symbol on the door. The spell is unlocked after completing Madam Kogawa's Assignment 2.

Door #1: Unicorn Door

For the unicorn door, you need to stop the pendulum when it reaches the leftmost symbol (while facing the stained glass) on the wooden beam. If done successfully, you will be able to unlock the unicorn door and get access to the room with a chest inside.

Open the chest to get an item to add in your collection!

How to Open Other Clock Tower Doors

Use Arrento Momentum to Open Other Doors

There are other locked doors found beyond the secret staircase of the Clock Tower. The staircase can be accessed from a locked door found left of the unicorn door.

You need to use Alohomora to unlock the door and get access to the secret staircase. Once you open the lock, climb the staircase to reach the other locked doors.

Clock Tower Symbol Order

The order of the symbols is as follows (from left to right while facing the stained glass): unicorn, owl face, twin dragons, scarab.

Door #2: Owl Face

To unlock the second door, use Arresto Momentum on the pendulum when it swings in front of the owl face symbol.

The owl face door is located at the left side of the wooden catwalk. You will be able to locate a chest inside the room after unlocking the owl face door.

Door #3: Twin Dragons

To unlock the third door, use Arresto Momentum on the pendulum when it swings in front of the twin dragons symbol.

The twin dragons door is found next to the pendulum. You simply need to descend a small set of wooden stairs to reach the door. More loot can be obtained inside the room.

Door #4: Scarab

To unlock the fourth door, use Arresto Momentum on the pendulum when it swings in front of the scarab symbol.

The scarab door is located inside a room located along the stairs, which you can find as you climb the wooden staircase.

You can cast Arresto Momentum from the same area where you opened the twin dragons door then climb up the stair to unlock the scarab door.

Head inside and you will be able to discover and solve a Hogwarts Secret!
