At the Tree of Life, the amount and position of the dirt on Marina's face changes between shots.
Elwood's beard changes from dark red to a much lighter reddish orange by the end of the movie.
When Ridley leaves the dungeon, his lantern is alternately open and closed between shots.
As Ridley consults the map before entering the dragon's cave, everyone else changes position between shots.
Marina fumbles with a magic dust bag and manages to throw some at Halvarth. As Marina throws the dust, she drops the bag to the ground and runs to Ridley's side. When she reaches Ridley, and Halvarth is getting up again, the magic dust bag is with her again.
The portal Damodar uses to return the Staff to Profion links to a point behind the mages. When Ridley exits a portal at the same location, he is standing somewhere entirely different, but the portals can be independent.
When Marina is on the floor reaching for the scroll in the Thieves Guild, Damodar appears to step on it just as she grabs it. His foot actually misses, so she holds it there and pretends it's stuck.
At the entrance to the dungeon, Elwood is obviously pulled back by a cable when he touches the Wall Of Force. His waist bends and flies back faster than the rest of him, even though his whole body hit the wall at once.
When Damodar is crouching to pull Snails out of the rug trap, the letter "R" is visible, in chalk, inside the right greave of his armor.
The heavy shadow-simulating contouring makeup on Norda's cheekbones is quite obvious in scenes where real shadows wouldn't show, such as late at night in the forest.
During the gold dragon attack on Profion's Tower, some of the fireball attack footage is used more than once. Sometimes the footage is flipped.
When Damodar is holding Snails up on the castle, a combine harvester/ tractor is visible in a field in the background.
Often, when chanting spells, Profion's lips fail to remotely match the words being chanted.
