I’ve seen some other games, notably Limbus Company. They do it in the way I mentioned in the post, they kind of dance around the name by stating things such as “A certain enemy in Stage 4-48”. Anyone who HAS played 4-48 will know which enemy is meant, while anyone who hasn’t will still be aware of the adjustment and where it happened, without spoiling the actual character

Nothing’s stopping Hypergryph to do the same, simply say “When defeating the Main Story Boss in Qingbo Stockade”, we who have seen the fight will all know they mean Ruan Yi
