Spells of attraction are a very powerful set of spells. They deal with how others see you, or in the case they are casted on another person, how others see them.
When these spells backfire, or are cast incorrectly the results usually end up going against the caster in the worse possible way. In nearly all cases the caster becomes uglier and uglier.
For this reason, the exact ingredients must be used for each spell, and the spells cast exactly as stated.
