"Essential Tip # 1: You must have an unobstructed view of your subject in order to properly cast the Tarantallegra.
Essential Tip # 2: In order to make a subject dance, it must first possess legs (a spell for growing legts appears in the advanced CAST-A-SPELL training handbook.
—Tips on casting, Cast-a-Spell handbook[2]
In order to be successfully cast, the spell requires a clear, unobstructed view of the target. The spell works on both living and inanimate targets, but the target must possess legs for the spell to work properly, otherwise, the spell may provoke an undesired reaction reaction out of legless targets, such as in the case of the eruption of Mt. Vesuvius.[2]


The Tarantella is a dance originating in Italy. It was believed to cure the effects of the bite of a Tarantula by causing the victim to sweat out the toxin. It wasn't until centuries later that scientists determined the Black Widow was actually the venomous spider in question; people merely blamed the Tarantula because of its size.[4] Allegra may be derived from allegro, a musical tempo meaning "quick and lively"; or simply from the word "leg" as this is the only body part affected by the jinx.
