Continuity mistake: When Airk is agonising he stares at Madmartigan, as front and back angles prove. Then he dies and bends his head to the right, but from the angle shot from the back -which is the same angle used seconds before - he remains in the previous position.
Continuity mistake: Before Airk is killed, Madmartigan stares at the fight with his hair soaking wet and messed up. When he runs to talk to Airk, ten seconds later, his hair is nicely brushed backwards. (01:52:24)
Continuity mistake: On the cart, Madmartigan is face-up with a baddie on top of him. Madmartigan punches him with his right fist so the baddie should fall backwards or to the left. However, shot changes and not only is Madmartigan magically standing up, but the baddie is falling to the right, as if the punch came from a totally different position.
Continuity mistake: After Elora and Willow's shield crashes inside the house, a man on the left walks towards the entrance and stops. A shot later he is a couple meters away repeating the previous walk.
Continuity mistake: When Fin gives Willow the book of magic, the people around rearrange themselves and come much closer together when the shot changes.
Continuity mistake: When Kaiya is bathing Elora, the boy is toying with a necklace, hands raised. A shot later they're lowered and the necklace is gone.
Continuity mistake: When Willow is sliding alone on the shield, Elora's blanket swaps between being brown in the close-ups to grey in the wide shots.
Continuity mistake: When Bavmorda lies on the floor after being spun around by Fin Raziel, her right arm changes position 3 times between shots.
Continuity mistake: When Bavmorda is choking Fin, Fin reaches for her neck, but a shot later her right hand is grabbing Bavmorda's hand. (01:54:03)
Continuity mistake: When Madmartigan kills the troll, the entrance to the castle changes style and the torch on the right disappears.
Continuity mistake: When Fin Raziel enters Madmardigan and Willow's cage, marks on the snow inside suddenly appear between shots.
Continuity mistake: When Madmartigan is about to kill Kael, he has blood around his nose and mouth. A second later it's gone.
Continuity mistake: When Willow jumps on the shield, the snow on Mad's back disappears between shots.
Continuity mistake: When Madmartigan kicks the troll he disappears from the ledge.
Continuity mistake: After Fin is almost killed, Bavmorda and Willow talk, the way the blanket folds over his hand and the amount of loose blanket on the right differs noticeably between shots. (01:56:53)
Continuity mistake: When Willow jumps on the shield it's clean. When Madmartigan jumps on it's covered with snow. It's not snowing at all, and even if there was a mild snowfall, it couldn't have covered the shield so fast.
Continuity mistake: When Willow burns a troll and it transforms into a blob of raw-sticky-flesh with two heads sticking out, he kicks it and in a mere frame it becomes a brownish ball that looks like a roasted turkey.
Continuity mistake: When Elora is put on the cradle of branches in the river, two big branches in front of her swap from straight to fallen between angles.
Answer: Bavmorda's ritual was the Ritual of Obliteration - a spell that is used to destroy a living spirit's essence or soul. Presuambly if she'd just killed Elora, the soul would have been later reborn into another baby.
