I try to and with a bit of tailoring with the material I've read in the Guide to Glorantha, the Glorantha Source Book, material from the Stafford Library and other sources. Now I do have some wierd ideas on how heroquesting works but that is a topic for another day.
Now on wyters, they are still scary powerful when released to thier full potential but don't wyters have issues with regaining magic points. Ie have to have worshipers sacrifice for them to regain it. Plus wyters also generally are try to stay with in the bounds of thier city/community and are more useful for fending off dark spirits and curses that target the area, you know the things referred to as temple magic (something a step above rune magic, which is what the Lunars weaponized with their Colleges of Magic and Argrath took and refined with Sartar Magical Units)
