Dance of Death

I looked this up as I just listed it in a now 90+ list of magic spells,

Yes, the dance is a weasel thing, but I listed it as a human spell, to cause the death of an onlooker, by causing cardiac arrest or a massive stroke. It's in the Restricted Section of the library at Domdaniel in the Black Forest.

To even get to the magic school would be quite an undertaking. Once there , you'd have to have clearance to access that section of the library.
