Flying and Invisibility George

I would choose flight because there are several possibilities for how it would happen, magical levitation and shapeshifting being my favorites. Invisibility would not always corrupt at first but the temptation would be very great. If you have read/seen the LOTR trilogy and The Hobbit you will know what I mean.  For the WNB i'm going to be advertise a shapeshifting elf named Alencaras the raven who can turn into a raven and has Hawkeye style archery skills. I think ravens are sort of "animal supervillains" because they are used as spies for many fantasy villains (a sad assumption) and have a very macabre appearance that inspires dread in many people. 

This is what I mean about what a power may lead to. Gollum dies jumping into a vulcano to save "his precious" which is the reason he can have longer life and invisibility.

Changing into a raven would be my preffered way to fly as they are my favorite animals.
