I use a Holy Freeze Cursed Heph that applies Amplify Damage to all enemies almost instantly. With that in mind, does -enemy physical resist make much of a difference or are there diminishing returns? I'm only concerned with PVE and I use also Sigil: Lethargy for bosses. I do not use a Sunder.

Thanks!

It won’t really make a noticeable difference imo, amp is -100 so even if monsters have 50 dr they’re at -50 right off the rip, which is more than enough

Do you have bone break sunder?
If not, amp is only -20% DR vs immunes, so other sources of -DR% matter more

Vs mobs amped down to -50%, having an extra 10% pen is still 6.67% dmg increase.

But you know everything is about to change after next patch. Right now you probably don't need more dmg.
-DR% will matter much more when you deal 1/10th of the dmg you are used to deal, and once amp triggers less often, and once lethargy doesn't have -dr% anymore.

Thank you!

I don't have bone break and that's true, phys immune things like wraiths do take longer to kill. Yes my whole build will have to be revamped if I keep it past next patch, thanks!

He makes good point didn’t take this into considering but even with phys immune once my amp is applied they still get mopped up fast enough, I didn’t use a sunder on the way to 99 and I had no issues
