Same with the first review. I think you're a veteran already! But if I tried to nitpick something it was probably the long paragraphs in the part where he described his ritual. The mood you set in the prologue, the mystery and cultic vibes, were overshadowed by the scientificality of the ritual described. I like it, but it could be more random and bizzare like Amil had to jump 6.5 times or use blood that came from his toes. Next the good one.
The plot hooked me, not gonna lie. I think it is a book that is reliant on your created universe. You wrote a whole dam of books, I'm envious. The weird grape that grew on his wrist was also such a weird thing; I like it, I made a short story about someone with a glowing butt, so weird shits like that interest me.
Next I was surprised when I saw your pen name in the prologue. Mr. Alchemist, what is the secret to gold transmutation? I'm in dire need of gas money.
Next, I thought it was set in a normal world but after planars and whatnot was mentioned, I realized it was in a different world with it's own set of logic. I just don't know if its out in the open rules or something only few people know of.
Next is the characters, I'll mainly focus on Amil. I think he deserved whatever happened to him lol. Who says he had to conduct a ritual? Also did it with such a high improvisation. Does he have a balls of steel? Not only that he's lazy as shit in disposing the used tools, he didn't even used google on what steps to do. He only consulted the Alchemist after he he stubbed his toe. You're such a good tempered person, if I was you I would already blocked him.
Overall, I like your story. The mystery, the email format, and the rituals.
VERDICT: NOT POISON - GOOD FOR LORE-LOVING FOLKS
