About Soul Stones[]
Soul stones can be equipped by monsters to increase their stats. A monster can equip only one soul stone, which can be replaced or dropped if needed.
You can gain a soul stone from any monster by destroying it. The monster will be gone permanently and will give a soul stone based on its element.
