Let’s cut to the chase. This guide will show you how to beat Heidne in Octopath Traveler 0, specifically for the Flamegrace region. She’s literally right outside the city.

Here’s a video on how I got the job done. I learned from my mistakes when I fought her in Sunshade:

Beating her takes the exact same steps from the Sunshade encounter. All that’s changed is that her weaknesses are different (now Ice is a weakness):

  • While she’s attacking normally, use normal attacks to build up your Boost.
  • Keep doing this and healing when your HP gets low. She’s strong as hell.
  • When she goes into Overdrive mode, unleash your Boost and attack with her weakness consecutively. Do not use a Skill. Just attack in rapid succession normally to put her in Break. This will daze her.
  • Then, unleash every skill with the leftover Burst you have for her weaknesses.
  • Do not let her use her finishing move in Overdrive as every single party member will take hard damage.

Once you master this routine, you should take her down with hardly any effort. Otherwise, you’re gonna get smashed.

Good luck, travelers!
