I’m enjoying playing through Arthur DiBianca’s The Wand with a friend. (In fact, we’ve been playing it for over a year together. It is very tightly constructed!)
We’re stuck and would love some help!
We have nine of the twelve arcane pairs and have not figured out what to do with the grandfather clock beyond setting it to 3, 6, 9, and 12. The soldier and the invisible flap in the cistern are also complete mysteries to us.
For the grandfather clock: once you solve a certain other puzzle, you’ll be told explicitly what time to set it to.
For the cistern: you need a spell that interacts with Secret Doors. You probably already have one of those, right? How many other Secret Doors spells are there?
