A few games ago an Inquisitor I was maneuvering as master used a necromancy spell to drain characteristic from a poor player (yeah...he wasn't the nicest or more "light aligned" inquisitor around, if you were wondering...actually a warlock necromancer with Deads' Blood).
Now, his characteristic would have dropped to 0, BUT we had no idea on how to work out such circumstance, so, for that game only, we chose to let characteristic drain reach a minimum of 1.
I'd like to ask the community if anyone knows if somewhere in the books there's any information about what happens if a characteristic is reduced to 0. If there isn't how about we write here ideas on how to work out such circumstance?
Waiting for feedback!
