Immunity from prosecution?

[Ludens]

Throw regular inquisitors at them until they lose all hope and curse God.. at which point your grand inquisitor should start piling up the kindling...

I think he already did. He is an atheist. You can't get much worse than that. The cause can be either bishops and cardinals or low zeal, or both. Perhaps you should let the inquisitor increase the religious fervour of the province before trying again.

Could well be the zeal factor - I don't recall any bishops hanging around and certainly no cardinals.

@Davidian: ooh, yes you can persecute kings - that's what makes Grand Inquisitors so deadly to Catholic factions. That and the fact you can just keep trying until he passes through the ultra-devout phase and becomes an atheist, after which his resistance seems to decrease a few percentage points each failed attempt until you get him.

It's perhaps just as well you can't fry Orthodox, Muslim or Pagan factions. Too unbalancing by half.

Thanks for the thoughts!

The single biggest factor during inquisitions is zeal, not so much the targets piety. With less than about 50% zeal your chances are greatly reduced. Bishops in the province also reduce your chances considerably.
