Continuity mistake: Xena leaves Darius' house, where she forgets her chakram. Then there's a shot of her riding Argo, with the chakram attached to her hip. Later Darius shows up to bring the 'missing' chakram to her.
Death Mask - S1-E23
Continuity mistake: When Xena and Toris are in the dungeon and the guards come in, Xena's boots change for a moment, then change back.
Continuity mistake: In the scene where the young woman is going to commit suicide, Xena shows her a necklace. In the wide shot Xena is showing the wood part. In the close up you see the emblem.
Continuity mistake: When Xena and Callisto charge each other on horseback, Callisto cuts Xena's right arm. When Xena turns Argo around, the cut has switched to her left arm.
Beware Greeks Bearing Gifts - S1-E12
Continuity mistake: In the first battle, Xena throws the chakram and it lands in a guy's chest. We see her kick another warrior with her chakram on her belt. Then she runs and pulls it out of the 1st warrior. (00:07:35)
Continuity mistake: Xena's sword is partially out of the scabbard in the frontal shot yet fully in the scabbard in the over the shoulder shot. (00:01:20)
Continuity mistake: When Xena starts chasing down Callisto after the attempt on the Oracle's life she has her sword in the sheath on her back, as can be plainly seen when she jumps on Argo. A couple of seconds later, there are a few shots of her charging after Callisto without her sword, which comes back in the sheath once the chase gets in open field. (00:23:00)
Continuity mistake: When Callisto and Xena first battle on horseback, Xena knocks Callisto's sword to the ground and Callisto escapes. When Callisto is training with Theodorus and the army at their hideout, her sword has reappeared, although she didn't pick it back up at the village.
