So allow me to explain what Zenovia actually did:

She absorbed the spirits that stayed with her and asked them to become a boon for her allies. This isn't really 'magic'. The spirits themselves are sentient beings that basically do what they like. As a Spirit Walker, Zenovia can ask them to do things for her. Asking entities for assistance isn't magic. It'd be similar to asking Eru for help.
