The Converted Fringe Tower in Elden Ring is a tricky one to unlock. Unlike the other sorcerer towers, this building requires additional gear in order to open. Accessing the Converted Fringe Tower requires a specific gesture and helmet, so prepare to spend some time unlocking items.
The Converted Fringe Tower in Elden Ring contains a hint that reads: May erudition light the way! To solve this puzzle and unlock the Converted Fringe Tower, you must have the Erudition gesture and a Glintstone Crown. Stand in front of the statue, equip the Glintstone Crown, and use the Erudition gesture. You may need kebun binatang to use the gesture while already gesturing to activate the second part of the emote. Now, if you don’t know where any of that is, let’s break it down into steps.
Firstly, to acquire the Erudition gesture, you must give Thop an Academy Glintstone Key. You will recall that a Glintstone Key is needed in order to gain access to the Raya Lucaria Academy. A second Glintstone Key can be found on a chandelier above the Church of the Cuckoo Site of Grace. Reaching this key requires a bit of work, as you must navigate across the rooftops of the Academy.
