If you're stuck in the Wyll questline in Baldur's Gate 3, you're not alone. Many players have encountered this issue after accidentally using gaseous form and ending up in dragon challenges. The problem is that one of the Ravenguard allies accuses you of being a traitor, and Wyll hasn't given any new dialogue or interactions since then.
One possible solution is to check your inventory for a book called "The Legend of Ansur." This book was given to you by Cordula Eltan after you convinced the group that Mizora is lying. Reading this book might trigger the questline to advance properly if it's stuck.
If you don't have "The Legend of Ansur" in your inventory, reloading a previous save may be your last resort. However, it's important to note that reloading a save will erase any progress made since that save, so make sure you've saved your game frequently.
Saving Wyll's dad is another possible solution, but it's unclear how that would affect the Wyll questline. Before attempting to save his dad, it's recommended that you speak to Wyll and try to find out more information about his situation.
In conclusion, there are several possible solutions to the Wyll exclamation mark questline in Baldur's Gate 3. Try checking for "The Legend of Ansur" and reading it first, but if that doesn't work, reloading a previous save may be necessary. Saving Wyll's dad is another option, but more information is needed before attempting that.
