Addressing Enfys Nest unique protection stacking

i was curious, does this bonus protection trigger on DOTs too? say if a Zader team hits her with a bunch of undispellable DOTs, doesn't that mean every turn her unique would be triggered at least 3x, making her effectively immortal (other than insta kill moves.... actually wait, pretty sure IPD's blow up move wouldn't actually kill her since that deals massive dmg, not exactly insta kill...)?
