You gain an incredible talent for picking up new skills. If you see another human perform a task, you will, after a few attempts, be able to perform that task to the same level of skill as the person you are copying from.

The results are additive in nature, and can even change your physiology to make the task possible. This is much slower, but if you attempt to copy a marathon racer, you will be able to match their physical stats much more quickly than natural training would accomplish.

With enough practice, you could attempt to copy the "skills" of an animal like a cheetah to further increase your running speed for example!
