This Seeking Tech guide will show you how to get the Down but Not Gone trophy in Jeanne d’Arc. For this to unlock, you have to use Revivify on an eliminated party member during battle.
To get this skill, you can combine Healing Wind 2 with Cure, or HP Recovery 2 with Magic Attack +10. It is easier to combine Healing Wind 2 with Cure. You can purchase Cure in shops after stage 17. I already did a video on how you can get Healing Wind 2. You can find a link to it below:
Alternatively, you can simply wait until you get to the post-game. Once you get there, complete the Free Combat stage in Alrond Wood to earn the Revivify spell.
Afterwards, equip this spell to a mage and then use it to revive someone in order to unlock this trophy.
