i may need to progress through the story farther, i just unlocked talents last night. but my biggest trouble is dadaelin keys. no clue how those go in. im assuming its to do with a spell i dont know yet
You mean once you get the flying key to the cabinet? When you interact with it at the cabinet it will show it flying around . Eventually it will cross the keyhole and you "smack" it into the keyhole. It tells you at the bottom of the screen what button to hit. (PS it's X)
