College of Necromancin' Dancin'

This college follows the example of a legendary necromancer who turned the world on its head and made the masses dance as part of his army of the dead. Raise an army of the dead, make the living dance to your tune, and grow the ranks of your army as you defeat your enemies. 

This class was based off a number of songs from my favorite band, Bear Ghost. Specifically:
Necromancin' Dancin'
When I'm Dead
The Steven Bradley
and
After Me, the Flood
