It's rather easy now, the biggest killer was the 2 ticks of searing flames + modulation combo and that's gone entirely. Just play it down calmly and avoid discs and breath at all costs. As mentioned before, bring a Swiftness Potion if necessary. If you can't beat Atramedes 4.1 you might have other issues you might want to fix before pushing for Al'Akir, Nef, Council or Cho'gall.
