you were walking through a mysterious cave when you encountered a Deathclaw. The Deathclaw scratched your arm and then seemed to snicker as it disappeared into the cave, you left the cave, but suddenly the pain was gone, so you touched the spot… and felt scales. You looked at your arms and saw that there were several patches of scales all over them. You were becoming a Deathclaw, though more of a humanoid one, being that you will still be standing upright rather than being hunched over.
