• A rope. You drop in through a hole, and a rope is how you climb back out.
• Something for demon, behemoth and banshee — they live down there.

The chest is 8 floors under the surface. Going down over it, this is what each floor uses:

1. 2 down: down through stairs.
2. 3 down: down through stairs.
3. 4 down: down through stairs.
4. 5 down: down through a hole.
5. 6 down: down through a hole.
6. 7 down: down through stairs.

• 1 — the way in: stairs, 2 down
• → — the treasure lies this way

• 2 — stairs, 3 down
• → — the treasure lies this way

• 3 — stairs, 4 down
• → — the treasure lies this way

• 4 — a hole, 5 down
• → — the treasure lies this way

• 5 — a hole, 6 down
• → — the treasure lies this way

• 6 — stairs, 7 down
• → — the treasure lies this way

Some floors are not on the list: their way down is further off than the rest, and that stretch you have to find yourself.

• 1-3 — the chests
• 4 — Demon Quest Reward ON
• 5 — a tile to step on

There are 3 chests here under 3 quest numbers, so you can take them all.
