This is another possible exit for the characters.
The walls of this chamber are slippery
and unclimbable, and furthermore the
slime mold which covers them has a high
acid content, burning exposed flesh for 1-3
points on contact.

There are several ways by which players
might reach the chimney 20 feet from the
floor. The ant bridge from 8 or stacked giant
fungus logs from 15 or 16 could suffice. A
human pyramid could do it, provided it is
constructed intelligently (strongest on the
bottom, lightest on the top.), and at
least 6 people are used to form it.
Resourceful players may come up with
other feasible methods. Note that a jump
spell only allows a 10-foot vertical leap.

The chimney is about 4 feet wide, and a
series of ledges make it easy to climb, even
for a non-thief. The chimney goes up 120
feet to a dead end. However, when a character
or characters have gone to the top and
ascertained that the chimney is a dead end,
the person(s) will be attacked half-way
down on his or her way back by a huge trapdoor
spider which will leap out from behind
its secret door, surprising on a 1-5 (d6). It will
attack the lead person, if more than 1 are
present. Characters will be at -2 to hit while
fighting in the chimney, due to the constricted
quarters and the necessity of hanging
on.

The spider’s lair is a chamber about 5 feet
in diameter, 60 feet up from the opening in
the ceiling below. Amidst the brush and litter
of the spider’s nest is a small leather
pouch, still attached to the belt the owner
wore. In the pouch are 27 EP
and 2 base 500 gems.

There is one small crawlway exit from the
spider’s lair, a tight, winding tunnel that
leads up 40 feet to the spider’s secret trapdoor
exit to the surface. This is concealed
behind a fallen tree in an overgrown beech
grove.
