>Flat effect, even when excited or scared it doesn't show, unless it is intense enough that she smiles or gets angry, but again her usual demeanour is flat face with monote voice
>Hyperfixation on leveling up, obsession with it, seems to be a thing that's on her mind all the time.
>Misunderstands situations and people constantly, seems to have issues reading social cues or seeing things from other people's point of view showing lack of empathy (not affectionate empathy, she has that just like actual autists do, she has horrible cognitive empathy which is accurate to autists in real life) doesn't understand why her obsession with leveling up seems creepy, when she honks the horn to spawn enemies and it upsets Patrick, she thinks he is upset because she forgot to use -san suffix. When she gets a terrifying dragon she assumes people would love it, and when they don't she thinks it'S because those people are bad with animals
I'm convinced Dolkness is an autist as they come, everything lines up. It was probably not the author's intend, but she's a good example of an autistic anime girl. Even igoring the whole isekai into video game thing, she just acts strange/abnormal that can't be hand-waved by her situation.
