Victim Attribute Stats
Toughness
Toughness increases your overall Health Points (HP); it has no impact on damage reduction.
One point of Toughness is equivalent to 1.11 points of HP.
All Victims start with 111 HP by default.
So having 20 toughness means 133 HP; a Victim with 50 toughness has 167 HP.
Although maxing out toughness limits your ability to do other things, having 167 HP makes you very hard to takedown by anyone except Bubba.
Ana has the highest base Toughness of 35 and coupled with her damage reduction ability, makes for a particularly tanky and resilient Victim.
