The World Lies in Ruins, and the Evil God Patches It Up

[Game transmigration + Lovecraftian horror + eldritch god corruption + dark church] A gaming enthusiast is playing a game when a monster disguised as a friend sends him to another world of swords and magic. The good news: He has a golden finger, a game die that can predict fortune and misfortune. As long as he doesn't go looking for death, he's unlikely to die in the starting village. The bad news: This isn't an ordinary fantasy world. It's a Lovecraftian one. Worse still, a certain eldritch god has already set its sights on him the moment he transmigrated. As an apostle of an eldritch god, Chloe can borrow its power to perform miracles. The price is corruption and mutation. At this rate, becoming a tentacle monster is probably only a matter of time.
