Horror spells

[Quitti]

Dream horror is a useful unrest raiser if you have the slaves to spend since the unrest generation stays in the province until they have time to patrol it. It is also anonymous. Still best bet to raise unrest is spam rain of toads into their forts with mages, since they will get diseased. Like Trumanator said, Horror seed is somewhat useless since it requires a MR check, so you'd need to stack penetration items to make it even marginally useful. Send horror is your mainstay to kill off armies and such from these spells, lesser horros are generally not worth the slaves/mage time. Against Nieflheim it might not work very well (or at all), since the horrors are not cold immune, and against Abysia it's also a bit dubious since they are not fire immune, but work better than against Niefelheim.
