i plan on making a zealot and i can't find the rules on what the insanity will do if sloted as a talent. The back of the card just says "you can attach an insanity card to this sheet as if it were a talent'.

what book and page is this rule printed?

I think the benefit lies in the zealot's ability. So exhaust the insanity and gain something (not sure, what specifically, but you only have to look for his/ her special ability).

The implication here is that you haven't been using your career abilities, that's not good...

From the Player's Guide (something any self-respecting player of WFRP should have because it's dirt cheap as a PDF, but prettier to look at in paper form):

"Career Ability: Once per session, you may exhaust your insanity talent to add fortune dice to any check equal to the severity of the insanity. The insanity automatically refreshes at the end of the current act."

You should also consider the following:

Zealot
Rules: See Liber Fanatica #7 for various faith alternatives to the 'plain old jane' as well as how to integrate Omens from Signs of Faith into your Zealot character.

Consider purchasing the following item from Signs of Faith: a Standard and/or holy symbol from p.37 of Signs of Faith.. They both have additional benefits for things that you can use.

You may wish to look into a background organization from the old 2e Career Compendium: Brotherhood of St. Soeren of the Sword – CC:235

jh

thank you all for the input i dont know why i didnt look at the career ability i guess i flaked lol. i think i was set on finding it in a book and had my blinders on.

Indeed, I dearly miss casually browsing stuff in 3rd ed. the way I used to...

Don't worry angrydragon, I do it all the time! inconsistent is how I role *puts on shades*
