Guide for NextGenWalkthroughs Played on Xbox 360, but guide can be used for the PS3, PS2, and PC versions as well. Maybe even the Wii… This part just shows you how to get to the Astronomy tower, where you then are ambushed by Malfoys dumb slaves. After you take care of them and finish a puzzle, you get to play as Ron for a bit. You have to take him to Slughorn’s office to make an antidote for the love potion Ron accidentaly took.
