Okay!

The last step of character generation is a special/magic item that will give you a D6 in some situations. What do you think she should have? Enchanted leather bracers? Magic sunglasses?

It's an item of defense.
Perhaps the tattoo, but if you want it to be separated and looseable then a ring.
If it's going to be more specific then it's defense against magic, and if even more specific, then against magical mental manipulation

A ring of defense against magic. 👍
