Have you studied the effects of schools and domains? What tags are added to the class when you add those? Can you add the same tags in a script?
Oh, and
will transition to whatever class added a custom class ability (it doesn't work in many places other than a custom class ability) - that can replace
Code:
hero.childfound[cHelpMAH].
so that if you want to re-use this ability for a second class, you don't have to re-work the script to figure out which of those classes it was added to.
