In RobM's example, the Bullet-1 against no armor in this case would do 1D of Injury, whose Severity would range between 1-3, since Bullet is defined as Total Hits / 2 = Severity. This would then translate to 1D to 3D points of actual injury points applied to C1, C2, & C3.
Someone set me straight if I'm wrong about this, but I don't think the above is correct at all. I made the text bold.
Bullet-1 does 1D of Injury, yes. Roll 1D, and take that damage from C1, C2, or C3 as a whole die. If this is the first time the target has been hit, then damage to C1, C2, or C3 is rolled randomly.
Severity isn't used until a character with Medic skill attempts to heal the hurt character.
Like this...
Crazy NPC is shot by Johns' revolver, doing Bullet-1 damage. Roll 1D damage, and it's a 6. Randomly, we take off 6 points from the Crazy NPC's DEX, giving him physicals 929.
Now, let's say the police drop a net on the Crazy NPC and take him into custody.
If no one treats the wound, it will heal, automatically, in three days. Crazy NPC will be back up to 989 on his physicals.
But, the police let a doc see him.
Step 1: Hit Location.
Roll on page 222, on the Hit Location table, to see where the character is wounded. We roll a 7, which tells us that the character was injured in the torso (if we roll an 11 or 12 on this table, then Severity automatically equals 1, which is a graze).
Step 2: Severity.
If the wound isn't automatically a graze as noted in Step 1, then we divide damage by 2 to get the severity. 6 / 2 = 3.
Severity = 3.
Step 3: Diagnosis.
A medic cannot treat a wound, except to stabilize a patient (stop the bleeding, pain relief), until a diagnosis is made.
A medic will roll the diagnosis task. Note that I am unsure where the difficulty for the Diagnosis task is found. In one example provided in the book, the diagnosis task difficulty is 1D random (1D to 6D difficulty). It may be different for a gunshot wound.
Success on the diagnosis task tells the medic the severity of the wound. Failure means the Ref gives the medic an incorrect severity.
Step 4: Treatment.
Severity = Difficulty for the Treatment task. In the case of this Crazy NPC, the Severity is 3D, so it will be a 3D treatment task.
To repair an injured anatomic location
Severity (nD) < DEX + Medic
Uncertain (1D)
Step 5: Healing.
A successful Treatment task sets the character along the path of healing. The character will be fully healed in Severity squared days.
For the Crazy NPC, this will be 9 days, but we already know that the can heal completely in 3 days naturally, so that's how long it will take him.
If his Severity had been 1, then healing time could have been shortened to 1 day.
The Katana is Slash-2 (=2D), but Wound Severity for Slash is Cuts/3, which would make the actual damage range 1D to 4D in terms of actual injury points applied to C1, C2, & C3.
No. Read up on the Medical skill, page 165. Severity is only used to guide those tasks (Treatment difficulty, healing time, etc).
Note that Cut damage is nasty because it does indicated damage
per turn, not just once, like Bullet damage.
And, I think that's wonky. Bullets can tear a person up just like cuts. You can bleed to death from both types of wounds.
