Your Power of Sorcery should enable you to burst the door open, but it will use up a great deal of WILLPOWER points to break the lock. You have no way of telling how many WILLPOWER points will be required, and once committed to this spell you will have to follow it through to the finish.
If you still wish to use Sorcery to open the door, turn to 114.
If you have the Power of Alchemy and would rather use that to open the door, turn to 170.
If you wish to enter the open archway to the right, turn to 163.
