I actually beat them first try, though I lost Shadowheart and Gale in the process. I’ve already burned through Gale’s scroll of True Res so I’m not sure how I’m going to get him back.
I'm actually not sure if Gale has a different revivify mechanic, but the talkative skeleton you find from the Overgrown Ruins secret room should be able to bring him back, and you can otherwise buy revivify scrolls off him by using the trade button on the bottom left of the screen during dialogue.
