Demon Hunting in Fog City: What the Heck Are Hextech Runes?

(Hextech runes + demon hunting + Cthulhu + sequence advancement. Different Hextech runes can be combined to produce unbelievably powerful effects.) Luo Wen transmigrated to a parallel world's City of Fog and became a demon hunter. But while other demon hunters relied on schemes, tricks, and supernatural powers, Luo Wen hunted demons with Hextech runes. [Prismatic Jeweled Gauntlet]: Your abilities can critically strike. Luo Wen: Got it! I use my revolver to cast an ability called “Basic Attack”! The System was dumbfounded as it watched a high-ranking demon's head get blown apart by a single shot. “Wait, what? Is that how you're supposed to use runes?” [Prismatic: Jack of All Trades]: Your basic attacks grant Ability Power, and your abilities grant Attack Damage. Luo Wen: Got it! Watch me use a “Basic Attack” called an ability! I'll step on my own left foot with my right and ascend to godhood! System: Host, that's an exploit! You'll get banned! Fog shrouded the streets, and demons lurked in the shadows. Luo Wen had only wanted to rely on the System and enjoy a carefree life with all his needs provided for. But gradually, one bizarre title after another appeared beside his name: “Demon Slayer,” “Arcane Machine Gun,” “Protector of Red and Blue,” “Dr. Mundo,” and more. Only later did he understand that the demons were merely a facade. Beneath them lay an even darker, more rotten truth. “Fine.” Luo Wen shrugged and raised his revolver, aiming it at the evil god. “I may not like demons, but I like you even less.”
