Black Knight Quest/Spoiler

First head west from the ground level of the abandoned house. Turn north as if heading towards the Amazon Camp, but instead of turning north by the river turn south. There will be a dead tree which upon 'using' you receive key number 5010. Return to the abandoned house and go down one level.

To the left will be a single slime spawn behind a door. Head south from the stairs and use the key to unlock the door, head down the ladder.

Drop down another level.

From here go east then turn south and drop another level.

Here head south and rope up one level.

Go south and be prepared to face a few skeletons then drop down either hole.

In this level there are four beholders. The first one is to the east and north. There is another just south of the first. The last two are pretty close together and it is not difficult to have both attack you simultaneously. Head towards the northern one and drop one level.

Here you will encounter the Door of Expertise for level 50. Head north and kill the single skeleton. A little bit further north of the skeleton are two more beholders. Kill them and proceed north to the teleporter. The teleport leads to one floor above you.

This is the dangerous and famous Black Knight room. Two scorpions and two beholders spawn close to the teleporter but may wander close to the spot you appear on after teleporting. You appear at the north end of the circular room and the Black Knight spawns near the south of the room so unless you run south standing still the paladins or mages could kill the lesser creatures without luring the Black Knight earlier than wanted. Kill the Black Knight then look around.

The room is circular with fire fields all around the edges with about six in the middle. To the north and south are dead trees in the corners of the room. The two southern trees yield the Crown Shield and Crown Armor while the two northern trees give nothing.

At the south of the room is the teleporter leading back to the single skeleton and double beholder room just prior to the BK.
