well from what I noticed my strafe was hitting significantly less changing my xbow's stat of all stat 9%+ignore def 60% to boss 60%+9% crit when they should of really did the same damage consider I ignored 100% def before and after I ignored only 40%.
If I did my math correctly
v1s has 50% def, with ignore 100% I got 0% and with ignore 40% I got 30%
my boss set damage is 140% without any potentials from just empress set bonus+10% fury, so with the 60% boss damage I would of had total of 42.86% boost multiplying it to 70% of my original damage I should have my 100% damage again making it no different from my original potential, well since I doubt that all stat 9% made 200k~ damage difference, and even if spirit link is additive instead of multiplicative with the potentials I should be doing 97% of my damage which the 200k~ difference clearly does not justify that. On empress itself I about 80% of my original damage which matches correctly. V1 instructors however does not match at all whatsoever. A ds friend of mine also said he had not noticed any difference when using demon impact. I had always cubed for ignore def potentials so I didn't really go calculating anything and noticed till now when I switched from ignore def to boss dmg.
Edit: tested today, definitely does not work at all. I got boss dmg 70% and ignore def 30% now, tested which only gave me the damage if ignore def worked. Boss damage does not work, only on empress. Still unsure about v2s
