She has it during the flashback of the Snow Wraith attack in "Dragon Eye of the Beholder, Part 2", where she beats the dragon with it after it grabs hold of her arm. When the Snow Wraith tosses her into a snow bank, her staff is left on top of the snow, and rolls down the bank. Back in the present day, she threatens the dragon with her staff, finally getting it to bite it and leave one of its teeth in the wood.
In "Big Man on Berk", she uses it to hypnotize Fishlegs, but he later snaps it in two and throws it off the cliff. She's unable to break his hypnosis without it.
In "Crushing It", she grabs a hold of Hiccup while he's spying on his father with the crook in her staff, demanding that Hiccup do something about Stoick's mood swings.
