I have a novel that is listed as High Fantasy Dark Action. but I label it personally as Graphic Horror because there are scenes that make the Saw movies and Game of Thrones look G-rated and I've never gotten anything about how it breaches conduct because I have all of those chapters labeled as mature, so...there is a scene for it on Tapas, but it's the side-road in the tracks you can go. I have scenes that graphically depict scenes of torture as the MC of the novel is the villain, and is ruthless, bloodthirsty and has no sense of mercy and its one of my most popular books. So, it takes some work, but you can get some dark action in.
