Just a quick question: In my recent game I converted to Lollard and established the religious head as my vassal. Crusades have already been triggered, but I am not able to request a one. Are there any mechanics to initiate a crusade? Is anything different from the base game where I do it like a 'regular' war declaration?
For testing I switched to Waldensian and was able to call a crusade with me being the religion's head. After switching to Paulician I was only able to call a crusade when being the religious head, it was not possible with another character holding the office.
Thanks for the help!
If you're talking about the SoA 'Request Crusade' hard-coded feature that doesn't work with custom crusade CB implementations, then no, you won't be able to do that (except when you can -- don't ask). I suppose we could someday (i.e., after patch 2.8) implement a 3rd-party diplo-decision to request a crusade from your religious head against an independent ruler with a hostile religion whom controls territory containing a valid crusade target kingdom (i.e., that would meet the requirements for the crusade CB).
