Here's a question about the rules covering Stun guns.
The Stun Gun stats on the chart says both Stun in the CRIT line and as a Feature. The Stun Feature says that it "inflicts stress instead of damage".
What exactly does this mean? Does this mean that all damage from the Stun gun is always stress, and that a Critical causes the opponent's stress to drop to zero? If that's the case, how does one determine whether a Stun gun attack does a Critical, as the chart doesn't indicate how many successes are required for the Critical?
Thanks, in advance.
