I just quickly looked at my Crusher and… I am not sure anymore. The weapon card states 128 damage for the light attack, but the damage profile relative to that number is
- Unarmored: 160 (125%)
- Infested: 160 (125%)
- Flak: 119 (93%, based on Penetration stat)
- Unyielding: 128 (100%)
- Carapace: 59 (45%, based on Penetration stat)
- Maniac: 96 (75%)
And from the patch notes
So I’m inclined to say… it depends on the weapon. I think most weapons would do 100% to unarmored (unless they have a stat that explicitly alters their unarmored modifier, like the Devil’s Claw swords), but it’ll likely vary.
So, in typical Darktide fashion… clear as mud
