Witchaven II: Blood Vengeance/Level 15: Lungs of Hell

A flight spell or two will serve you well in the initial lava area, if you've carried one over. If not, make good use of fire resistance until you can grab the one that's across the tightrope near the start. Don't try to get the two-handed sword without flying; there's a spike hidden under it ready to kill you. Once you're airborne, you can collect the brass key, the sword and the various spells in this area before heading through the passage to the south, which is locked with the brass key.

In the room you eventually reach, the dark floor pad under the invisibility potion will open up a closet full of even more goodies to arm yourself with for the final battle. The other dark floor pad under the health potion will open up the way forward and you can proceed.

When you get past the place with the lava fall, look for a grey door. Go through it and follow the passage until you see a forest of nasty spikes. Touch them and you die, so use your flight spell again and fly well above them. Beyond you can grab an ankh, magic shield, Nuke scroll and glass key, then teleport. This is one-way.

To the north is a door, head through it but be very careful doing so. As soon as you're through the door, head right, not forward, or you'll be caught by a spike trap. You can see where it is afterwards if you go down the stairs. There's another ankh in this room, and also a black key door. Go ahead and try out your Open Doors spell on this one (you should have found a scroll in the lava area near the start). There are some weapons, potions and gold inside. Before you leave, you can also jump on the pillar with the quiver of arrows to open another room with a bunch of pike axes and a fireball scroll.

Head back to the teleport exit (remembering the spikes near the door) and through the glass key door. Carefully follow this passage, there are more spike traps along it. When you come to what seems like a dead end, open it as it is a secret door. Continue on, but again, be careful of spike pits! Finally, there's the black key... aren't you glad you used your spell instead of having to backtrack to that door? The exit from the caves is in sight, too, so head out of the tunnel.

Fight your way up the huge ziggurat to the summit. Circle around the top to find the ivory key, then head inside. Seize the pentagram and... Suddenly you are teleported somewhere else. This is it, Cirae-Argoth's inner sanctum. The very last fight, so don't hold anything back: potions, spells, all your best weapons. When Cirae-Argoth dies, grab the horned skull that she drops and sit back to enjoy your victory, such as it turns out to be.

You have won the game.

Tips and secrets:
 * The southeast corner of the starting area contains a niche with some treasure.
 * When you get to the big ziggurat, check the back side of it to find some scrolls.
 * The castle walls surrounding the ziggurat area aren't just for show, either—fly up there and you'll find lots of goodies as well as some enemies.
