This Seeking Tech guide will explain how you can earn the Hanging on by a Thread trophy in Jeanne d’Arc.
You can easily get this trophy on the first stage. At the start of the fight, you should head to the northeast bridge.
On the eastern side, your goal is to defeat the Orc Knight while keeping your distance away from the two Orc enemies that will be chasing your party.
Jeanne should be your main attacker, while Liane should stay at a distance and heal Jeanne if necessary.
After beating the Orc Knight, you should defeat one of the Orcs. Afterwards, keep your distance from the last remaining enemy so that your party won’t counterattack him to death.
On the tenth turn, you can then close in and finish off the last enemy to complete the stage and earn the trophy.
