Are there any rules for these? I know that some rituals are sustainable by healing surges, but thats about all I've been able to find. Is there any way to dispel a permenant sustained ritual? Or even just a regularily sustained ritual? Perhaps through some sort of an item focus?

What about interrupting one? Does damaging the caster interrupt it? I can see a DM using a skill challenge to this effect, but was wondering if there was another way.

Any info or insights would be appreciated.
