That did make more sense than the helmet. And Nate and Dani both had reasons to have taught her to use as much as possible of whatever animal they hunted and killed.
"Can I use my powers? Or I should stick to old-school hunting techniques?" If nothing else, seeing where she was most likely to find her prey could be helpful. She didn't plan on using at Death projection, though. She didn't like doing it unless it was necessary, and it wouldn't help much with the sort of things Valkyrie was going to teach her.
