Ignore the last replies about “converted damage ignoring armor”, that has been patched.
Keep in mind that sth like 35 flat weapon damage will be multiplied by ~3000% physical damage, then 200% weapon damage, then multiplied further by reducing enemy phys res below zero.
And then amplified as a crit.
So (35 x 3000% x 200% x 1.15) = 2415 dmg, after dire bear that would be ~200 dmg effectively, on a non-crit vs Calla or Ravager.
But most enemies don’t have that much armor or 87% phys res 
The small values of 10-20 damage, I consider to be absolutely pointless, at least on “only” 200% weapon damage.
