Damage Reduction - how is it calculated ?

[Mister Wonderful]

Dear fellow keepers

is there an official ruling on the order in which damage reduction effects are calculated ?

Taking the Star Vampire as an example

• 4 points of armor
• bullets deal halved damage

Example: A shot from a revolver doing 10 points of damage on our poor Star Vampire

Version 1  (armor first, reduction second):   10 damage  - 4 points armor , then halved  = 3 Points damage

Version 2  (reduction first, armor second:  10 damage halved, then reduced by 4 points of armor  = 1 Point damage

thank you

I used the Version 2 approach to calculating damage when my group of Investigator fought a Star Vampire in our DDT campaign. But I'm not sure where this is in the rules, if it's mentioned at all.

The armor examples (CoC7e p.112) and physics seem to lend themselves towards option #1. Example: If the Star Vampire were say, in a car, the armor provided by the car would almost certainly reduce the damage before the halving. Same with a mummy wearing a flack vest... standing behind a 1" thick wooden door.

True.

#1 If it were all cosmic pseudo-real spacey matter there wouldnt be any actual armor to really stop the bullet. It would just pass thru and not interact much with the Star Vampire.
