When Adora introduces Castaspella to her brother Adam, Castaspella's legs are colored flesh tone instead of the blue leggings she wears in every other scene.
Castaspella says the Eldritch mist blocks all her spells, so she cannot get in to Whispering Woods or free anyone from inside. But when she gets the Eldritch book, she does manage to teleport herself, He-Man and She-Ra into the Woods before casting a spell to remove the mist.
When Adora holds aloft her magic sword, the background is a night sky instead of day. A moment later Adam starts his transformation and it is daylight behind him.
