Shattered Kingdoms

Eh, as it is now, voodoo is basically worthless, if you don't have a doll you have no real chance of killing anyone but a mage and it leaves you incredibly vulnerable. Unless you're in a tribunal surrounded by a swarm of your own guards or have a few friends with you to guard you. It's tough to justify using it, seeing as you're completely exposed to gates.
As an example, on a necromancer char of mine, a griffon shaman failed to kill me in a voodoo, I asked the nearest priest to cure my maledictions and make a gate to said shaman and killed him without the use of undead, since the shaman is completely paralyzed for a good while there is nothing they can do to defend themselves against even the weakest attacks that don't deflect.
