What God helps odyssey repel circes spells when he encounters them on the way to circes hall?

In Homer's "Odyssey," Hermes aids Odysseus in repelling Circe's spells. He provides him with a magical herb called "moly," which protects him from Circe's enchantments and ensures that he remains unaffected by her magic. This intervention allows Odysseus to confront Circe and eventually persuade her to help him on his journey home.
