Explosives directly attached to target:

p. 198 says the DV gets doubled.

p. 436 says the targets Armor gets halved.

Is it both? Or, if not, which one applies?

[Namikaze]

I think that it's either.  The result is the same, whether the DV is doubled or not.  Probably one of many typos and inconsistencies.

[ZeConster]

How is the result the same? DV x2 and Armor/2 are different things.

[Kanly]

Yeah it's definitely not the same. After doing some math, I'd say I'd prefer both - which is entirely possible, since the explosive's DV and AP are two different matters; the confusion only comes from the two rules being in two different chapters.

EDIT: in SR4, it's both - direct attaching means DV*2 and Armor/2 both. Maybe someone else was wondering as well

[Namikaze]

Hmm...  yeah you guys are right.  I wasn't doing my math correctly.

Test Scenario: DV 10, Armor 10.  DV x2, Armor x1 results in 10 damage.  DV x1, Armor x1/2 results in 5 damage.  So yeah...  my mistake!  As pointed out, it is both in SR4, so I'm sure that's the intention.

[ZeConster]

DV 10, Armor 10, DV x2, Armor x1 doesn't result in 10 damage: it results in 20 pre-soak damage and (Structure + 10) soak dice.

Very basic question on Edge, but I can't seem to find it anywhere in the book... Let's say I have an Edge of 3 and I spend a point to add 3 dice to a test. Now I have 2 Edge remaining. Later on if I spend another point, do I add only 2 dice to a test, or do I add the original 'attribute value' of 3 dice?

[Kanly]

Original 3.

[S.K. Ren]

Lets say I have a partial Cyberarm with no upgrades and my base strength is 7. Which tests do I use my normal strength and which tests do I use the Cyberarm's strength? Would I only use the cyberarm's strength if it was a matter of gripping something and my normal strength for everything else?

Similarly if I have a Partial Cyber arm with a Modified Agility rating of 9 and my base Agility is 1, which do I use for shooting my pistol? Do I take the average?

[Crunch]

If the test involves only the cyberarm you would use the Cyberarms stats only (the books example for this is leading with the arm in a melee attack).

If the test involves "close coordination" you use the lowest stat.

If the test is "anything else" you use the average of all applicable limbs with the torso counting as a limb.

What falls in each category is left pretty much entirely up to the GM.

[Top Dog]

For a partial arm, the living part will do enough of the swinging to count as requiring average, I'd think. Still, as Crunch says, ultimately it's a GM call when you get to specific cases like that. Myself I'd probably use average for the sword swing and the cyberarm for the gun.

[Crunch]

Similarly if I have a Partial Cyber arm with a Modified Agility rating of 9 and my base Agility is 1, which do I use for shooting my pistol? Do I take the average?

The GM could rule that you use the arms 9 Agility (if he ruled that shooting a pistol used only the dominant hand)

Or she could rule that you use your 1 Agility (if they ruled that shooting a pistol required close coordination between between the hand holding the pistol, the torso and legs absorbing the recoil and turning to follow the target etc).

Or it could be ruled to be the average of all limbs if it's ruled to be neither only the arm nor close coordination. In that case you would take 1+1+1+1+9/5 and get 2.6 and then round up to 3.

[Top Dog]

Or she could rule that you use your 1 Agility (if they ruled that shooting a pistol required close coordination between between the hand holding the pistol, the torso and legs absorbing the recoil and turning to follow the target etc).

At the risk of making this a non-quick answer, "leading an attack with your cyberarm" is specifically listed as using only the cyberarm stats, so this wouldn't be the case; as far as the rules are concerned you can do it with just the arm. Since it's a partial cyberlimb you might need to split it with the rest of your arm though. Further debate on this might ask for it's own topic.

Leading an attack could be read to apply to melee attacks. That would certainly be the common English usage of the phrase. Like everything else in the Cyberarm rules it will fundamentally come down to how the passage is read by the GM.

Further debate should probably go to another thread, but the fundamental answer will be that the Cyberarm limb rules are so vague and badly written that all you can really do is make sure to get your GM to answer your questions before committing to a build (or if you're a GM to make sure you're clear on your rulings before a player makes choices based on a different reading than yours). 

[Kanly]

A non-quick answer to the cyberarm topic:

I'd say attacks use the whole arm - not from a scientific point of view, but gamebalance. I think most cyberarms are bought to have incredible Str or Agi for your attacks and implanted weapons.
You could install +3 str and agi in a partial arm and still have 4 cap for a weapon. And it's 0.55 Ess less than a full arm.
If you want the Condition Box, 2 partials for 0.9 E give the same as a full for 1 E.

So something needs to give a full arm some edge over a partial and I think it's gotta be the attack bonus.
