Why are Slimes only found in caves? A FATE core supplement. You are a Slime living on the ceiling of a cave. Below you is food. The problem is you have no skills but you do have two stunts that cost a FATE point to invoke; - Mimicry: Can mimic a creature - Absorb: Can absorb a skill or stunt from a creature. Eat more of the same creature to gain a better understanding of their physiology. This will make your mimicry more convincing and your skills/stunts more powerful but there is only so much you can learn from a single creature. Because of this you should always keep looking for a bigger creature but Slimes are vulnerable when they’re young. May be in the cave there is a clan of Goblins or Kobolds the Slime could covertly integrate themselves into. It’s a good idea to do some world building before you start a campaign so players know their Slimes environment. When the time comes and you can mimic a sentient creature. Head off out of the cave to start a new adventure. It maybe wise to not leave home without a basic understand of a common language.
