Continuity mistake: Season: 1, episode: 16 "Bloodline". As two soldiers of Darken Rahl approach the plains of Morrow, they break a magical shield which catches them on fire. Two frightened soldiers run away, and the commander shoots one. Keep an eye on the commander - he is still pointing the crossbow even after the soldier dies. The next shot, however, has his crossbow loaded with another arrow, daring anyone else to run away.
Prophecy (1) - S1-E1
Continuity mistake: At the beginning of the episode, Kahlan Amnell, and her sister, Dennee Amnell, are escaping the soldiers of Darken Rahl on horseback. There is one scene, as the ladies are riding, that you should take notice of how many times Denee and Kahlan change positions while riding away from the soldiers in several quick shots - sometimes Denee leads while other times she is behind; then, sometimes they are riding side by side. Also take notice that Denee gets struck by an arrow while she is leading Kahlan in the chase. Then you see Kahlan looking over her shoulder in terror because her sister has been shot.
Revealing mistake: In practically all the episodes, where we see Darken Rahl wearing a sleeveless shirt, there are visible vaccination scars on his shoulders.
Visible crew/equipment: In the beginning of the episode, when Kahlan and Richard are walking in the forest, a crew member with equipment can be seen there right behind them for a second.
Visible crew/equipment: In the beginning of the episode a crew member can be seen with a camera stand, modern clothes and a white helmet for a couple seconds. He is behind Kahlan and Richard.
Conversion - S1-E15
Continuity mistake: Richard, Kahlan, Devlin and Chase shoot arrows in to two guards at the entrance of the fortress of D'haran. Each guard takes two arrows apiece and falls to the ground. Richard and Chase runs past the two dead guards towards the entrance, and the arrows are no longer in the guards.
