Tensura: Not Enough Bosses

This is an official addon for [Tensura: Reincarnated](https://modrinth.com/mod/tensura-reincarnated) made by the official team themselves to add new bosses for their server's quest system. Therefore, by default, the bosses are not spawning naturally in the world. This addon currently adds: - Rimuru: At the stage of when he just finished obtaining the Orges in the series, before the Orc Disaster fight. - Carrion: At the stage of when he fights Milim in the series. - Luminous: At the stage of when she doesn't have any Ultimate Skills yet, at the end of anime season 3. Quick summaries of the boss's difficulty: - Rimuru: A bit harder than Orc Disaster, below Charybdis. - Carrion: Above Charybdis, around Hinata. - Luminous: Final boss, much harder than Hinata.
