Easy. You limit his magic to 2 unless he becomes an initiate of your cult, because you want an incentive to convince him to join...
More members means more tithes to pay for those fancy temples, more people to send out to do dirty jobs for you, and more worship energy going to your God. So why would a priest ever give something for free when restricting it benefits both himself and his deity?
Ok, but he'ld serve his community better if he had Bludgeon 6
If he becomes an acolyte or priest his time becomes diverrted from his primary task and becomes tied to preaching and ministering.
Perhaps I'm trying to attach a deeper sense of realism to the rules here, perhaps thats a bad thing.
I kind of worry - probably unnecessarily that Mongoose go back to RQ2 cult view, where the cult ties to culture become light weight.
Heroquest hate or like it opened up the cults and modelled them well within the culture and gave that sense of realism, which can be pretty easily to adopt to RQ.
Take 3rd Age Sartar the majority of the people worship Orlanth or Ernalda, effectivelly a state religion, effectivelly every one is lay member by being born a Sartarite. 95% of the population take Initiation into Orlanth or Ernalda, it is a step to Manhood/womanhood.
Acolytes, Priest, Lords follow specialised sub cults of Orlanth associated to common professions.
An acolyte of Orstan (Orlanth) allfather is the clan's Carpenter , an acolyte of Starkval (Orlanth) allfather commands the clans Fyrd, the Priest of Dar sits in the seat of the clan chief advised by the clan ring.
The can providing only the sub cults and cults it needs to make its way in the world. Other cults rarely encrouching, only where their specialised skills are required:
Along side The Upland Marsh the cult of Humakt thrives, near the Footprint and Snake Pipe Hollow Urox cult is strong, Issaries comes into his own where cities spring up.
Sheeeet, thats the long way around of saying,
Shouldn't each cult provide only the rune magic its followers need, and the only limitation placed upon them being an expected service to the cult.
Why shouldn't the Carpenter have bladesharp 8 for his plane, saws and Chisels, if he has got the time and inclination to learn the magic why should he be restricted, it serves the comunity for him to beable to do his job well.
I could witter on about cultures pulling together and working as a unit to support each other... yeeez but thats taking toooo much from heroquest
