Corrected entry: It is shown that Demon sorcerers can't touch good magic with feeling extreme pain. In the episode when Jackie fights with the Earth Demon, Jackie is wearing magic armour that was made with good magic, yet somehow all throughout the fight the Earth Demon can hold, grab, or hit Jackie without experiencing any negative effect.
Corrected entry: When Shendu has the first 11 1/2 talismans, he can't transform into his full dragon self yet, even though he has the Rat. But later on when he fights Jackie and looses the Rat, he suddenly reverts back to a statue.
Correction: He needs all twelve talismans to transform into the dragon, but he only needs the Rat to stay that way.
Correction: Only Demon Sorcerers are harmed by touching good magic, not Demons themselves.
