Just a quick reality-check, here, to be sure I'm reading Damage Compensator correctly.
The words "...may ignore a number of boxes (both Physical and Stun) equal to the compensator's rating..." seem, to me, to mean that if you have Damage Compensator 10 your Wound Penalties for each track would start at -1 on the 13th box of damage to a single track, regardless of what the other track is doing.
Or, in other words, if you've just taken a flashbang to the face for 9 Stun and a shot from a Panther XL for another 12 Physical you would be, despite being nearly dead, acting with a -0 Wound Penalty.
If this is accurate, then I'm thinking Damage Compensator is going right up on my shopping list next to Pain Editor and Platelet Factory.
