The Staff of Ages is a magical object used by Hex in the Ben 10 series. It is said that only a master magician can use it. It first appeared in the episode Lucky Girl.
Like Charmcaster's bag, it is a source of magic. As said before, the staff was used by Charmcaster and Hex allowing them to use more powerful magical abilities.
The staff itself is wooden, and has a bird-like head on top with a ring that runs through its eyes.
In the original series, it belonged to Hex. He claimed that it takes a master magician to use the magical abilities of the staff. Charmcaster tried to use it, but it wouldn't work due to her intermediary skills in magic. However, Gwen was able to use it in Tough Luck, against Charmcaster.
