A spell of dance and deterrence

Arachnodemons, 
Hear my terms —  
Taste no blood.
You shall learn
My Body is of
No concern.

Mark my words. 
Don't forget, 
I have my own venom yet — 
Belladonna's Tarantella,
Hex you back with pirouettes.

The tarantella  is a rapid whirling dance, believed to cure victims of tarantula bites. 

As silly as this poem may sound, countless studies have shown the benefits of exercise on physical and mental health. I needed a spell that incorporated physical movement so decided to write one about dance, as this art form has been historically associated with the supernatural :)
