emissarium

Can be used once a day: Call for the guardian angel Azazel and repeat the prayer of the underworld. Shout as loud as you can, God almighty and gracious forgive me because I only need the devil who feeds and lives from sin.

For every soul you kill, your magic gets +1 hitpoint damage.

Until 24 hours are up you wear the sign of the scapegoat which prevents you from using magic and which halves your hit points.
