I'm particular glad I got this miss for Zatanna (Who is officially sixteen in-game as of last month, in case people were asking about the age requirement) because she's been in the Death plane before. Back when the gates were first opened. Needless to say, it was not a pleasant experience the first time...but it also means she'll have some idea of what she's going up against this time.

In addition, if the locket has any magical aura/properties about it, pending interference from the plane itself, Zatanna might be able to sense its presence and thus help them further in their search.

She is also not without fears and concerns. Some of them are incredibly personal--if she passes by the cemetary, she wouldn't be fearing her own death, but the deaths of those she loves most. There's also the Helmet of Fate still haunting her to this very day, and the fear of being trapped inside forever. Individuals such as Klarion of Doctor Fate himself could show up to verbally torment her as well. So there are a lot of options.
