Hi, I'm also stock on this part I think. I really have no idea what to do lol. There are only two scarabs, and one is needed to be in place to enter the room which leads to the room with the other scarab and the trap wall, so unless there is a third scarab or a way to keep the door open it is literally impossible. I feel like either the game is bugged or I just can't find the third scarab. Really annoying because I was enjoying the game alot
