Engraved key in Baldur's Gate 3

An engraved key in the Dark Crypt will open the Heavy Oak Door. Go out of the bedroom into a corridor with several passages. On the quest, you need to move to the left to find two doors - one on the right and one on the left.

There are several chests in the room. In the room on the right side there is an engraved key that opens the door on the left. In the middle of the room is a tomb. Do not confuse it with the sarcophagus in which the withered one lies. An engraved key is hidden inside the tomb. Before you take it, switch to turn-by-turn mode by pressing Space and Shift. Make sure the characters pass the attention check and a button appears on the side of the column. Search the tomb. The trap will work. While you are in turn-based mode, quickly press or shoot the button. No character will be harmed as a result!

Now you can open the heavy oak door at coordinates X: -294 Y: -288.
