Calculating half and double damage

[Sunslinger]

Here some ideas how to handle weaknesses, Resistances and Attack weak spot.
I know parts of the topic have been discussed in the forum already. Here a try on a more comprehensive approach:
Damaging Weakness: damage is doubled before soaking.
Resistance: damage is halved after soak. Heroes/villains can spend one hero-/character-point to halve the damage before they soak.
Attack Weak Spot: damage is doubled after soak. Heroes/villains may spend one hero-/character-point to use the dice of their to-hit-roll also as their damage-roll.

In my opinion the focus should be on the soak. Because of that I generally apply the soak first. An exception should be the damaging weakness as that should make an attack form really dangerous and damaging for a character (therefore doubling first).
In addition a villain/hero with a Vulnerability against a usually harmless substance should only be allowed to soak against that form of attack as if he had a negating weakness against that form of attack too (as if he had Brawn x1). Otherwise a vulnerability would not be a substantial weakness for characters with high Brawn (x4 or higher).

Attack Weak Spot should apply BEFORE, soak as this allows more skilled characters to use their ability to find the weak point in and get through an opponent's defenses; instead of merely doing double damage to an attack that won't penetrate.
