Jules MacDuff is a witch introduced in The Sims 3: Supernatural. He lives with his family in Moonlight Falls. Jules lives with his parents Flint and Joanie MacDuff and his twin brother Joe and sisters Faith and Felicity. He only has three traits instead of four. He starts off with a level 2 athletic skill, level 3 in charisma and level 7 in alchemy. He has a wand and a copy of "Why do Vampires Suck?" in his inventory.
Jules is good friends with his mother, Joanie, his sister, Felicity and Branch Timbley, friends with his father, Flint MacDuff and sister, Faith. He is enemies with his twin brother, Joe, despite the fact that in his bio their rivalry is stated as being "all in good fun".
His bio states Jules is a daredevil, which also happens to be a trait and could be the trait he is missing. Jules has the same traits as his sister, Felicity, which may explain why they get along so well, even though Jules pulled a prank on her.
