Elden Ring is massive in size. To say that it's a large game is a bit of an understatement. From Software put a ton of time into the Lands Between, resulting in an extensively large area that is teeming with hidden bosses, secrets, and areas that are off-the-beaten-path. A great example of this is The Four Belfries, a strange landmark built upon a hill that sees four different stand-alone belfries reaching high into the sky.
At the base of each one of these belfries is a mysterious waygate, but players won't be able to simply walk up to these gates and transport through them. First, they'll need to unlock the mysterious seal that guards them, by using the Imp Statute nearby. Unfortunately, regular Stonesword Keys won't work on these special statues, they'll only accept Imbued Sword Keys. There are three of these special keys to be found in Elden Ring. Here's where players can snag them all.
Players won't have to look hard or travel far for the first Imbued Sword Key as it's actually found at The Four Belfries in Liurnia of the Lakes. Although there are only three waygates for players to unlock here, there are, in fact, four belfries that stand tall upon the hill. The fourth one, located at the very top of the hill, has a chest beneath it rather than its own Waygate. Inside the chest is the first Imbued Sword Key, which can be taken and used at any of the other belfry waygates, regardless of order.
To get the second Imbued Sword Key, players will need to unlock and enter the Raya Lucaria Academy. This can be done by snagging a special Glintstone Key to access the area. Once inside, players should progress to the Debate Parlor (where they will need to do battle with the Red Wolf of Radagon. Once defeated, players can access the Debate Parlor Site of Grace. From this Site of Grace, players should head out the door nearby and then to the left, heading up a staircase (past many enemies) and jumping off a railing on the left-hand side. Once there, players should head up the stairs before them, to the left, and over another railing to reach the rooftops of the academy.
Once on the roof, players should continue past the two nearby Marionettes and then up a nearby ladder. Players should be careful progressing down the pathway past the ladder as three flying enemies and a sorcerer stand in the way. Players can lock-on to the flying enemies, throw an object or use a bow to pull them one-by-one. At the end of the path, players can move right around the building and then down onto a nearby roof. From there, players should continue progressing down the rooftops until they see another Marionette enemy (with one patrolling off in the distance). Players can leap down and kill the Marionette closest to them and then immediately jump down to the right to land on another rooftop. There, in the small gazebo-like area at the end of the long roof section is a corpse containing the Imbued Sword Key.
The final Imbued Sword Key is located in the challenging zone of Caelid. Players will need to make their way to Sellia, Town of Sorcery and complete the brazier puzzle there to unearth the chest that contains the final key. Once players have lit all three braziers, the strange seals blocking the doors exiting the town, as well as the boss room and the nearby chests, will fall. Once this is done, players can head down to a chest in a small enclosure and snag the last Imbued Sword Key.
Once players have access to all three Imbued Sword Keys, they can open every gate available in The Four Belfries. Players can access these gates at any time as long as they have a key within their inventory and don't need to wait until they collect all of them. Here's a look at what lies below each belfry, starting at the one at the bottom-most part of the hill, and moving upward.
