Monster of Kaiden spawns various asian mythology-inspired monsters around your world. This is an Apocalypse style mod; that is to say, it will effect general gameplay. These monsters spawn commonly on the surface during daylight, meaning travel is risky.
That being said, it should be vanilla-friendly otherwise, if you can stand a more dangerous overworld.
So far, the monsters include:
Titan
A bloodthirsty giant that commonly spawns in most overworld biomes.
Yurei
A ghostly floating head which rarely spawns in most overworld biomes.
Teketeke
A vengeful spirit who lost the lower half of its body, which spawns at night.
More monsters will hopefully be added in the future.
Feel free to use this mod in any modpack, or mod showcase. But again, it might majorly effect gameplay.
