These are the parapet (or
sill), embrasures, and merlons set
atop a wall to provide cover
for bowmen. If the surface is not broad, a catwalk
(q.v.) must also be constructed.

Cellar excavation, ground
flooring, windows, interior walls, and additional doors are extra.
The cost to increase wall
thickness is 10% of initial cost per course of stone (1' thickness).

Murder
hole: This is a slit, crossletted slit, or similar opening in a floor
to
command a passageway below.
In combination with inner
portcullis, inner
wall slits, and pits, they
make an entrance possage in a gatehouse or
similar structure very unhealthy

DPV:
Q: What is a murder hole?
A: A murder hole is
an opening in a ceiling,
usually in a fortification,
from which a
defender can attack an intruder
with a
spear or other long, stabbing
weapon. It is
very hard to return an attack
made from a
murder hole. In the D&D
game, a murder
hole provides the attacker
with full cover
(-4 AC bonus). In the AD&D
game, a
murder hole provides 75%
cover (+7
defensive adjustment).

Q: How much does it
cost to build
Oriental structures? Where
can I
find building plans for
such structures?
A: The cost for an
Oriental-style structure
is the same as a comparable
structure in a
western campaign (see the
DMG,
page
107). Oriental “paper wall”
construction
costs about the same as
wooden construction
(85% -100% depending on
the quality
of the paper construction),
but is more
expensive to maintain (150%
of maintenance
costs). Try your local library
for
information on architecture;
ask the
librarian for books on any
of the following
subjects: castles, the Middle
Ages, medieval
warfare, medieval architecture,
Oriental
architecture, Japanese feudalism.
The
bibliography
on page 144 of Oriental
Adventures gives
a few specific titles to
ask about. See also the
two reference-book
articles on the Oriental
world in this issue
of DRAGON® Magazine.
