This a mob part of thre Majestic Mobs mod for 1.17.1 i am making the mod consists of 3 new biomes , 26 achieves, 4 new armors , tools and ores, and 30+ different mobs, still a work in progress but will be out soon :)

here is a video on how it spawns into your general gameplay during caving




has its own loot table that drops rare materials



mimics have a 4/20 chance of spawning compared to regular hostile mobs



mimics are actually 3 parts, the spawner placeholder, the block chest, the entity itself.
