How to open the heavy oak door in the crypt

As soon as you get into the crypt, inspect two doors: on the right and on the left.

There are several chests in the room - search them. To open the left door, you need to get an engraved key, which can be found in the room on the right.

What to do next :

1. Enter the room on the right.
2. In the middle you will see a sarcophagus in which the key is hidden. Don't touch it just yet. Place items on vents to prevent slime from escapingout. There are 6 holes in total.
3. After that, you can open the sarcophagus.
4. Get the key and sword.
5. Head towards the heavy oak door at coordinates X: -294 Y: -288.
6. Use the engraved key to open the door. You can also find a button in the room with a sarcophagus, on a column (if you have enough insight). Click on it to stop the deadly traps.

You can search the coffin without blocking the vents, but there's a good chance you could die. When you open the coffin without blocking the vents, slime is released that makes it difficult to move around. At this point, fire arrows begin to fly out from both sides of the room.

Along with the engraved key in the coffin you will find a rather powerful two-handed sword.
