Right at the start you get an ankh, so charge up and get ready for battle. Now head out into the mines.
Although the automap may look a touch mazey, it's much easier to follow than the previous two. Head to the north part of the map where you find two similar-looking treasure rooms with some stairs down and to the north. Being careful of the lava pit, you can head to the northmost point and collect the brass key. You should be able to make the jumps, barring glitches. Don't miss the ornate horn in this area, either.
Now head to the west area, through the brass key door. There are a lot of traps in this area; don't worry too much about the closing doors, but the fireballs may be a problem. Pull the chains on the walls to open the way down. On the other side of the big room is a balcony where the black key is, jump or fly to get to it. Along with the key, you can stock up on pike axes and fireball, nuke and freeze scrolls.
The pentagram is in the south area, through the black key door. This area is a lot more nondescript, a room with some pillars and lots of barrels, but there are plenty of enemies so don't get careless.
Now loop back around to near the start, drop into the lower passage where you can see the door, and fight your way into the final room. Enter the pentagram pad and prepare yourself for Cirae-Argoth's stronghold.
Tips and secrets:
- Near the start, there's a lowered area with a bunch of fireball scrolls.
- Go through the level counterclockwise. If you go clockwise, not only do you reach the key doors before the keys you need, there's also a blockade that will lower, causing you to have to follow the level in more of a C shape.
- On the approach to the brass key, break the big stained glass to find an ankh.
- In the round central part of the mines, you can find some goodies including a Nuke scroll.
