「マッハ3」(85%と55%と25%)以外かなり安定です。「マッハ3」の対策は「幻影」(主人公の奥義効果とネモネ) やジークの「3アビ」。
「竜の巣」(40%と10%)の対策はラインハルザの「3アビ」かジークの「2/3アビ」。40%のとこはラインハルザの「3アビ」が終わっても次のターンでジークの「2/3アビ」も丁度使えます。8:43
38%から10%まで: もしラインハルザが落ちたらサブから出てくるアンスリアの「1アビ」でダメージをだいぶ防げると思います。
RNG spots: All Mach 3 triggers (85% / 55% / 25%). Besides that it's pretty straightforward. Counters for Mach 3 are mirage buffs (MC CA effect or Nemone) along with Siegfried skill 3.
For Dragon's Nest (40% and 10%) triggers you soak them up with Reinhardtzar. Even if it runs out before you reach 40% (lack of DPT what not) you have 2 extra turns since Siegfried skill 2 and 3 pops back up right after. 8:43
If Reinhardtzar drops between 38-10% Anthuria can soak up most of the damage.
Your FA run will vary depending on your DPT since you need certain skills to align with certain triggers so adjust it based on it. I removed Michael and Belial for this video.
