Re: (TFT) My thoughts on the Fog spell



Rick,

   Thanks for the comments!  Ok, here goes ...

   As stated in the original email, the ideas for this Fog
spell were off of the top of my head and had not been play-
tested, so Im not surprised it would generated questions.

>	First the fST cost of the 3 versions of the spell are
>unclear to me.  The first number is the casting cost I assume

>spell?

Yeah, Im sorry - that's the shorthand I use.  When a spell has
a maintenance cost, I've usually presented it in the "slash"
format.  Under this format, a BLUR would cost 1/1 - 1 to cast
and 1 to maintain.

> Re: Cumulative Costs:
 
Yes, I had originally intended that maintenance cost increases
for each hour along an arithmetic series, ie the cost of 
maintaining the spell is not a single number, but constantly
rises.  So, for Light Fog, the first hour is free, the second
hour costs 1ST, the third hour costs 2ST, the fourth costs 3ST
and so on.

When casting Fog, the wizard is manipulating the forces of 
nature that causes natural fog to be generated, ie lowering 
the air temperature, increasing the humidity and/or dew
point (whatever it is that causes fog to created).  So the
fog is a by-product of the spell and not the actual spell.
Thats why it takes so long to form and then dissipate.

The idea behind the arithmetic series is that the wizard is
holding nature at bay while the fog is present.  I thought
this manipulation should get harder and harder as time goes
on, otherwise even a beginning wizard could maintain light
fog for 8 hours!  This just didnt make sense.

In the same vein, it didnt make sense to me to use the cost
per turn idea as then a wizard would not be able to maintain
fog long enough for it to be of any real use.

>	Does the casting wizard have to be within the

I hadn't thought about this: perhaps it would be a good idea
to have the wizard remain within the fog in order to maintain
it.

Good idea, I hadnt thought of this when I jotted the idea
down.  It is more along the lines of TFT to use different 
IQ levels for the different versions.

Rune lines?  I'm not familiar with that.  The idea for a
new class of spell (W) is interesting - I was trying to 
pick a class which came closest to the idea.

Well, lets see.  The wizard is holding the forces of nature
at bay while the fog is present, so any breezes that are in
the area would be routed around the fog. Within the fog, if
a wizard were to cast OPEN TUNNEL, a hex of clear air would
be generated, afterward fog from the surrounding hexes would
move into the open hex. If a wizard somehow creates a breeze,
I'd have to ponder on how that would be handled.

Larger is certainly do-able.  :)  Perhaps at a higher initial
cost though.  People can see a fair distance into Light Fog,
hence the LOS rules I threw in.  I've personally been in fog
so thick I couldn't see objects 10 feet in front of me. That's
some serious fog. Hence the idea of Heavy Fog, Medium Fog and
Light Fog.

I think I am coming around to this point of view as well.

This would fall in line with its classification of a Creation.
If it were a new class, such as Weather (W), Im not sure the
above would apply.

This is what I had originally intended.

Which is why I asked for comments from the list.  :)  BTW,
if we can agree on the background for the fog, perhaps 
other weather manipulations might be envisioned, such as
Snow, Rain, etc.  The only other thing that comes close
is the Magic Rainstorm.  But this is extremely localized.
It would be neat if we could think up some way for a 
wizard or group of wizards to affect the forces of nature
over a large area.

A Druid grove close to a farming community might be very
desirable in that case as the Druids could help to ensure
that rain arrives on a regular basis.  Also, the idea of
a group of wizards forming a tornado is interesting.
