Witchaven/Level 12

Be careful of the pool in front of the start! There is a spike pit of death in the middle of it.

First, go and collect the brass key. A quick way is to take the right-hand path and go through the teleport you'll soon encounter, taking you to the brass key room. Once you've got the key, go back to the teleport room, but this time continue past to find the pentagram area.

The pentagram is blocked off behind four square walls, and guarded by a Skeletal Witch. The black wall ornament over the water section of this room is an illusionary wall, behind which can be found the pull chain for making the pentagram accessible.

Now head into the office-like area to the southeast. A bookshelf here is a secret door, and behind it, following the stairs, you'll find a grey ornamental structure that is the brass door. You'll find an area full of skeletons, and the black key, which you can bring back to the black key door. Directly beyond the door are a Mino Drake and the exit.

Bonus Areas

 * One of the white stone ornamental panels on the return path from the brass key is a hidden door.
 * The second shield in the skeleton area past the brass key door is a death trap.
 * The hidden Hero Time helmet in the dark area behind the "office" desk is also trapped with lethal spikes. Flight is the only safe way to collect it.
 * However, if you hang to the furthest right side of the spot under the desk when you move forward, you will instead drop into another hidden chamber that contains a second, safe to collect Hero Time.
