First, let me thank everyone for their opinions. I see that there is a
clear split, with some people thinking one way and some people the
other. That in itself was a bit surprising - because I had played in
quite a few groups over the years, and there was no hint of a second
interpretation through all of them - until I joined my current group.
So (because of my experience) it SEEMED another one of those cases
where I wanted to turn to the DM and say "This must be considered one
of your House Rules, because everyone I've ever played with for 30+
years plays it the other way." But that's why I come to places like
this to get more opinions - "my experience" is still limited to a
dozen or so groups (with varying membership over time), and thus is
still a very small sample from the entire world of D&D.
My own experience matches up reasonably closely with Joanna's - that
this is a field of force that can move anywhere within the range of
the spell. It does not have a body, it does not weigh anything, it
does not stand on anything - you can send it up to the ceiling or down
a well with no trouble.
My current DM, though, has apparently always played with the other
interpretation throughout all the various groups HE has ever played
with. It essentially walks. It has a "Movement" rate, and that is a
Term Of Art in 3E that means walking. It doesn't have a "Fly Speed" or
a "Swim Speed" or a "Climb speed", so it can't do any of those things.
(Of course, the spell description was pretty consistent and it goes
well back before that became a Term Of Art.)
I generally stick to the direct sources when they are available, and
nothing in the PH from 1E or 2E or 3E was clarifying anything. Tonight
it occurred to me to go to a slightly different source (still Official
AFAICT), and I found something that sheds light on this (and also on
the question I asked a while back about a PERMANENT UNSEEN SERVANT).
In THE WIZARD'S SPELL COMPENDIUM they collected and organized all the
spells in 1E/2E. While most are presented just "as is", there are a
few spells that contain addition text. This is presented with a grey
background instead of a white background. You might just call it
"additional material". In some cases it gives a brief set of stats for
a monster that can be summoned by a spell. In other cases it gives
options the DM can use (which are clearly marked AS options). And in
still other cases, nothing at all is indicated. UNSEEN SERVANT is in
the last category.
Volume 4 of the Wizard's Spell Compendium, page 972, gives the UNSEEN
SERVANT spell. At the end (after even the Notes section, which says
that as far as rarity goes it is a "common spell"), there is one of
those Grey Background sections that goes like this:
"The UNSEEN SERVANT does not have any senses or powers of
reason. It is incapable of any action except following its
instructions to the letter. Thus, while it can be sent to the bottom
of a pool to grab whatever objects it encounters, it cannot be
directed to grab any gems or coins it might find.
A PERMANENT UNSEEN SERVANT always hovers within 30 feet of the
caster. If destroyed, it reforms in 2d10 rounds."
So - in 1E/2E it can explicitly go through water. It also "hovers",
which implies being in mid-air (i.e. not needing a surface). The
wording in 3E is similar enough that I would believe that they did not
intend to change that - but I would not assert that as being proven.
(The changed wording in PF suggests to me a deliberate change rather
than "Explaining more clearly something that was always the rule" -
but again, that's not proven. Maybe the PF guys were in the "It's
always had to walk on a surface" camp and they thought they were just
clarifying things.)
The bit about having no senses, however, seems hard to reconcile with
the servant being able to mend something, or even bring up "whatever
objects it encounters". Both of those activities would seem to REQUIRE
some rudimentary senses. How can it mend a rip in your sleeve if it
can't see or feel or otherwise locate the tear or feel the needle and
thread? How can it grab something it has "encountered" if it has no
sense of sight or feeling? How can it do pretty much ANYTHING? How
can it carry something somewhere, open a door or hold a chair if it
can't sense where they are? Can it lay it lay a fire if it can't
sense the pile of firewood or where the fireplace is? How can it
safely CLEAN an area?
So I think they are going after something slightly different here. I
think that it might be able to act on sensory data YOU have. If you
point to a door and tell it "open that door", it registers the door
because YOU have seen it (and made the decision about what to do). But
if there are 1000 pieces of gravel at the bottom of a well, with dirty
water preventing the caster from seeing what is there, you can't tell
it "bring up coins and gems" because it can't tell the difference
between an unseen (by the caster) gem and an unseen piece of gravel.
If the water was CLEAR, however, and the caster can SEE the gems, the
caster could say "Bring up that gem I'm pointing to." Since it's clear
in the caster's mind, the instruction can be carried out by the UNSEEN
SERVANT. This would often prevent it from carrying out instructions
like "go to the other side of this door and open it" since it does not
(by itself) sense where the doorknob, lever or other latching/locking
device is. But maybe that would work if the party had just come from
the other side of the door and the caster KNEW where the doorknob was.
Still, in 3E they talk about it being able to do things up to DC 10 as
long as they require no training. Finding an obvious mechanism to open
a door would seem to be something it should be able to do....
So - I don't want to take the "senses" stuff in the grey background
area as being literally true, but I still want to use the grey
background stuff to say that TSR (or at least the editor of WSC)
thought it was a very mobile force that can move anywhere in spell
range (though the air, through water, etc. - unless there is something
that would stop "force" effects). Talk about wanting my cake and
eating it too... Anyway, I don't think an UNSEEN SERVANT can go
through solid stone or a WALL OF FORCE, for example. I think you need
what 3E calls "Line Of Effect" (but of course they weren't using that
in 1E/2E, so maybe you CAN do that in a 1E/2E game). If "the strength
needed to carry 20 pounds" isn't enough to get through a solid
barrier, I think the barrier stops it.
Meanwhile, the last bit from the grey background stuff is clearly
where I had gotten the idea that a PERMANENT UNSEEN SERVANT would
reform if destroyed. So the party as a whole would not be limited to
the movement rate of the UNSEEN SERVANT as long as they were willing
to wait a few minutes for it to reform when they needed it. (Without
this aspect, creating a PUS would simply be throwing away XP for
essentially nothing since it would be out of range VERY quickly in
standard dungeon play.)
