The damage reduction doesn't apply to debuffs, so you can bring servants with those skills/NPs to help you.

Personally, I used Merlin, Robin Hood, and Jeanne on the first two waves and switched Robin Hood out for a friend's Waver on the last. I was able to take out 3000HP on the boss in one turn due to Waver's curse debuff stacking up.

Regarding less SSR options, I have a friend who used Hassan of Serenity. Halloween Elizabeth is also an option, since she has a burn debuff skill and a curse on her NP (though mine went down in the second layer when I tried this).
