Suicide Curse

A Suicide Curse is a powerful and horrific form of Necromancy. It involves the use of Necromantic powers to circumvent one of the strongest instincts a living being has, the drive for self-preservation. When effected by a Suicide Curse, a target will actively seek their own demise, irrespective of whether or not they actually wish to die.
The use of a Suicide Curse is a direct violation of the Sacrileges and any Adept found using one had better have an ironclad reason for using it.
Luckily, a Suicide Curse requires a substantial level of power and knowledge to use. Curses alone can take a hefty chunk of Kenosis or Magick out of those who cast them, but to cancel out one of the most primal and fundamental instincts human being has is especially challenging. 
For those few who are able to cast such a deadly supernatural attack, the target will become passive and seek to inflict mortal wounds on themselves. Depending on the type of Coven used, the person may or may not carry out additional orders or desires while in the act of destroying themselves (a Necromancer could order their victim to die in the act of killing someone else, turning them into kamikaze warriors, etc.). 
Most Suicide Curses affect only one person, although the greatest of Necromancers or Resurrectionists can cast infectious versions of the Curse. These Suicide Curses can be 'contagious,' passed along from one victim to another, usually by means of eye-contact or touching or simply word of mouth. These are the worst kinds of Curses imaginable and entire towns or populations can be wiped out very quickly through their use. 
Adepts and other Supernaturals will have a higher level of resistance to a Suicide Curse. Their own Supernatural nature will act as a counter-measure to it.
To date, the punishment for the blatant use of a Suicide Curse has been nothing less than life-imprisonment in an Oubliette.
