Mist spell and visibility modifiers, how to deal with Options

[Nefacio]

hello everyone,

The Mist spell from S&M says that it impossed a visibility modifier equal to the hits scored.
Reading the BBB I find the visibility modifiers for ranged attacks from a mist are detailed in a table there so they are basically those, but given a spell that creates a mist that has a variety of densities according to the hits scored I beilieve this has to work differently.

I couldnt find a rule written to deal with this situation, I know it can be simply adjust it with a bit of commmon sense, but I want to hear some opinions.

A true question I have is how the spell will affect others spell casted at LOS, will Mist spell imposse a penalty on those too?

Visibility modifiers apply to spellcasting tests involving LOS.

Anything that breaks LOS is useful against mages.

I think a more interesting question is how do the different vision types help against this spell? That's something I've been wondering.

From the Visibility Table on page 140 of the SR4 core rulebook ...

Light Mist: Normal Vision -2 / Low Light -1 / Thermo 0 / Ultrasound -1
Heavy Mist: Normal Vision -4 / Low Light -2 / Thermo -2 / Ultrasound -2

Just use those as a guideline.

However, the spell imposes a modifier based on the hits scored. It doesn't simulate a defined mist type--light or heavy. So, if you get 1 hit on the spell, then those looking through the mist get a -1. That doesn't match up with anything on the Visibility Table.

Just use those as a guideline for each of the different vision types. For example, a person with only normal vision takes the full penalty, but someone with low light vision might have a slightly lesser penalty.

Or ...

Treat the spell as written, being a magical effect, and rule that the various vision types are immaterial when determining the penalty.

Personally, I would just go with the second choice, which is, as you point out, the canon rule.

Heh, I see that you did. (IMG:style_emoticons/default/wink.gif)

Sure, the second idea is the easier way to handle it and won't bog down the game. Thanks for your opinion.
