Nightmare Fuel / The Acts of Caine

• Arkadeil in Heroes Die delivering a calm lecture to his students on how he will proceed to torture Lamorak: By cutting open part of his skin, sprinkling insect eggs inside, sewing it back in, and waiting for the bugs to hatch and burrow their way out.
• Blade of Tyshalle has a nasty disease that resembles rabies on steroids, the God of Dust and Ashes, and the scene where the avatars of said god Mind Rape the protagonist's daughter. The winner, however, would be the scene where the bad guys summon a demon who takes out a mortally wounded and expendable underling. The demon feeds off of terror and despair, and to keep that disemboweled sap alive, reaches into his rib cage and manually pumps the heart to keep his blood flowing.
• In a flashback in Caine Black Knife, most of what the Black Knives are capable of doing to their victims (like the Black Knife Kiss), but special mention goes to the Black Knives nailing Caine to a cross and forcing him to watch his comrades being graphically tortured.
