Does doing 999k on Empress guarantee absolute knockback and no DRs and attacks?

Jz saw a vid of a phantom soloing empress doing 999k dmg, knocking her back constantly so much so that she has no dr, no summons and whatever.

Now the question is, would a mercedes doing 999k on Empress be able to solo her by pinning her to 1 corner? say on the right side? without DRs, tornado,...

Thx for the reply.

Jz wondering if calmly or iathas has tried soloing empress.
