Drop Location

• The Enormous Greater-Than Sign

When Used

• From inventory, before The Oracle's major consultation:

You have no idea what this thing is for.

• From inventory, after consultation:

Following The Oracle's advice, you treat the plus sign as a book, and read it. It describes, in great detail, a place called the Dungeons of Doom. The first chapter teaches you that the Enormous Greater-Than Sign is actually the stairway leading to these dungeons, and the rest of the book teaches you how to recognize the items and monsters contained within its halls.

After you're done reading the book, it vanishes in a puff of obsolescence.

Notes

• Grants access to The Dungeons of Doom.

References
