If you have a:
Deadly (500%) + Throttle (50%) shotgun with
100% weapon exp (10%)
10 merits in shotgun mastery (10%)
Max damage from faction (10%)
Gun Shop perk (10%)
Property damage boost (2%)
Education damage boost (1%)
Education throat boost (10%)
Eviscerate (20%)
I'm probably missing some, but you get the idea. How does this work? If I remember correctly Eviscerate works differently from the normal damage boost so would it be adding everything up that isn't eviscerate then multiplying by 1.2?
