You can’t walk into Wyrm’s Rock Fortress in BG3.
Summary SCREENRANT VIDEO OF THE DAY SCROLL TO CONTINUE WITH CONTENT Before the party can enter the titular city of Baldur's Gate 3, they have to get past the guards at Wyrm's Rock Fortress - and that's no easy task. As with many situations in the game, there are multiple ways to approach this dilemma. However, choices can change everything in Baldur's Gate 3, so it's important to form a solid plan and understand the consequences of each step.
Solving A Murder Can Also Get You Through Wyrm's Rock Fortress In Baldur's Gate 3 It may take a little more effort, but it's also possible to gain access to Wyrm's Rock Fortress by aiding in a murder investigation, in case the party feels stealing an invitation is a morally objectionable decision in Baldur's Gate 3. In order to do so, they'll have to travel to Rivington, and follow their nose for rumor to the Open Hand Temple.
That's enough for Valeria. Return to her at Sharess' Caress, and she'll ask the party to escalate the case by sharing it with authorities inside Baldur's Gate. She'll give them a Lower City Pass to get through Wyrm's Rock Fortress, which the guards accept easily. This transitions into a new task, "Investigate the Murders," but the party already has a way into Baldur's Gate and doesn't need to progress the quest line in order to continue.
You Can Just Sneak Into Wyrm's Rock Fortress In Baldur's Gate 3 Of course, the party can just break into Wyrm's Rock Fortress. It's probably the most direct route, but also the most dangerous. Around the corner from the main entrance, there's a small crack in the wall. The party will have to jump to get there, but it's a long way down. Someone will have to cast feather fall to reach it safely.
