Andrui's Baneful Backfire (Wizard Spell)

This spell enables a wizard to protect his magi­cal property and enchantments from tampering by other spellcasters. The backfire can be cast on any magical item or object even temporarily endowed with magical properties (such as a char­acter that has been slowed).
The backfire remains dormant until such time as a character attempts to cast dispel magic on the object. The backfire not only causes the dispel to fail automatically, but the dispelling caster loses one memorized spell of a level equal to the spell or effect he was trying to dispel. If he has no such spell, the backfire causes him to lose a spell of the next lower level, until the caster has lost one spell or has no spell to lose.
For example, suppose that a 7th-level wizard is attempting to cast dispel magic on a door that has been wizard locked and is protected by the bane­ful backfire. Upon casting the dispel, the wizard instantly loses one 2nd-level spell (equal to the level of the wizard lock) and the door is still mag­ically sealed.
The baneful backfire is not effective against a spellcaster of a higher level than the wizard who cast it. In such a case, a successful dispel magic would dispel both the ward and the spell it was put in place to protect.
The physical component of the spell is a bit of cat fur and a piece of carpeting roughly three inches square.
