Collector Stone:
I can transform Scroll of Escape: Tower of Insolence info the Stone of Memory.
But that's not easy, so there is a chance I will not succeed.
As you probably know, Stone of Memory doesn't disappear after use, you can use it as much as you like.
If you already have a Scroll of Memory, I can exchange it for a Stone of Memory for a floor below.
Create Tower of Insolence' Stone of Memory Exchange Tower of Insolence' Stone of Memory for a Stone for a floor below
