001 Wonder Woman
How far is one square away? I think that its not adjacent, but that would be one square away to me. So is it 2 squares which has one square between them.

Maybe I am over thinking this.

It's adjacent characters pretty much with some more flexibility.

The way the trait is worded allows characters on different elevations, and sides of blocking terrain to benefit from the trait.

This. Filler.

Also, since she's friendly to herself and within one square, she also can use shape change via her defensive power.

If you look at the Queen's dial, you'll pretty much see that the Amazon Sisterhood is a Shield Wall. Very interesting design that might get destroyed by EE/PW. I want to use it as a proxy for Vikings. =)

Thanks for all of the responses!
