I'm gonna be honest, this feels incredibly like a revenge porn story made just to be a revenge porn, and I mean that in a bad way. Given the canon universe, if there's an individual that can fully heal a person's wounds, regardless of severity, they wouldn't be treated as a slave at all. Needless to say the cast gained information about what the healer class can do precisely because there was previous healers as well, and they would've known the healers can do more than just heal. The entire power-fantasy that the healer's abilities are basically the equivalent of a swiss-army knife is more than enough to break the worldbuilding. The entire rape thing felt like the author ran out of ideas on how the hero can be abused and just said "fuck it, hero semen gives people superpowers."
0/10, can't even praise it for the art. Ended up feeling more cringe than edge.
