Villager-Imposter(The idea for adding an unfinished illusioner to the game)

( There may be mistakes in the text,  I do not speak English at a high level)

A new Villager-Imposter will spawn in a village in which there are 5 Villagers with maximum discounts. This Villager reduces the reputation of the player and discounts disappear, and then the Villagers sell items at an inflated price. Villager-Imposter looks like an ordinary unemployed villager, but his appearance is slightly different. You should not try to kill him, the iron golem will protect him, because he thinks that this is an ordinary Villager. The player needs to declassify the Villager-Imposter (for example, throw a potion at him or click on him with a bucket of milk). After that, Villager-Imposter becomes illusioner . After defeating him , all discounts appear again . Also, the player can get more discounts and some kind of achievement.
