Blowing stuff up.

I have a question about the Blast rules in Spycraft. In the Blast rules, it says that blast incremeter is measured in squares, but on the Quality of the various blast weapons, it is listed in feet. For example, the 2000 lbs. iron HE bomb has BLS (100 ft.) Just to get it straight, 100 feet is the blast incremeter for this weapon?
But the question is about the incremeter itself. On a hit, the attacker chooses a 5 ft. square where the weapon lands. Is the full damage then applied to everything within 100 feet from this square, or is the total area covered by the first incremeter of the blast 100 feet wide?

I run it as the blast increment is the first radius at full damage.  so 100 ft out from the square is full damage then the next 100 is half, etc.

Afrodave's got it right. The conversion from squares to feet is pretty simple - the bomb in question has a blast increment of 20 squares, for example.

But the question is about the incremeter itself. On a hit, the attacker chooses a 5 ft. square where the weapon lands. Is the full damage then applied to everything within 100 feet from this square, or is the total area covered by the first incremeter of the blast 100 feet wide?

Full damage within the first increment (100 ft.), then reduced to 1/2 standard (rounded down) in each increment outward from there.

Hope that helps.

It suits me fine that the Blast is measured in feet, since I don't use a square grid when running combat.

After rereading the Blast rules, I get the impression that Ground Zero in a blast is as wide as the blast incremeter from side to side. Is this right? Or is the Blast Incremeter the range from the impact square that suffers the full damage? So in other words, is the blast incremeter of a blast the radius around the impact square, or is it the diameter of Ground Zero?  The text is a bit unclear on this...

Let's take an example bomb with a blast increment of say 20ft. Everything within 20ft of the bomb takes full damage, so it is the radius of Ground Zero.

Everything 21-40ft of the bomb takes 1/2 full damage
Everything 41-60ft of the bomb takes 1/4 full damage
Everything 61-80ft of the bomb takes 1/8 full damage

At each increment the damage is rounded down, so the increment at which the damage becomes 1 is the last. Beyond that there is no damage from the explosion.

Does that clear it up for you?

[Ferretz]

Yup, that clears it up. Thanks

This actually coincides with a question I was going to ask: barring the actual computer system usually associated with it, would these rules handle a "self destruct system" well enough?

Well aside from the detonation method I can't see anything to make a 'self destruct' different from any other explosion.

[Ezram]

Ah, it depends on the size of the estate I suppose.

Also, what explosives in this instance are most likely to be used? 

[Krensky]

Immaterial.

The classic "The base will self destruct in 30 seconds." Device isn't a weapon. It's a plot device.

[Ezram]

Actually, it's relevant to me. I like little details like that.

[Antilles]

In most cases, the highly unstable element known only as "handwaveium".

[Ezram]

Hm...

Really depends on whats self destruction doesn't it?  A mansion? Get some strategically placed semtex, or c4.  All old wooden shack, dynamite.   Some crackpot wth a dodgy self destruct system? Gotta go with a bunch of old hand grenades with their pins connected to a bit of string. Hell if the suitation warrants it, a small nuke might even do the job. 

Think about who is employing it, how much collateral damage they want, how sure they want to be that everythings dead, how much can they apply to the destruct system in terms of resources, etc...
