Erin has a long list. Wishes are good at giving people knowledge, abilities, talent, and powers. She has excellent vision and knowledge of cooking from a Favor, a subtle and vague sense-of-magic from a Gift, and the ability to speak any language from a Boon, as examples. Some examples of other peoples' powers are flight, healing, extra-sensory perception, supernatural strength and coordination and balance, telekinesis...

Wishes are also good at finding things, from finding the lost treasure of King Yu, to finding the answer to a challenging intellectual problem, to finding someone you could have a happy relationship with.
