We frequently use the D10 or percentile in our WFRP3 games.
It comes up most often for resolution suggestion of unresolved chaos star or unresolved comet effects. The player's guide had suggestions for these, so I made up a little chart with a d10 (although, I'm looking to expand it now ![]()
I also use a d30 for random skill selection inspiration. Sometimes I also draw from a deck of tarot cards or Williamsburg Aesop's Fable cards for inspiration as well (on the fly).
The percentile comes up when I need inspiration on a random item (I roll and approximate from the list in my house rules), and for career choice generation. As I keep my career sheets in binder pages (I got the 4/page negative archival pages), they're not something that we can just "randomly draw from."
We have a mystic in the party, so I also use the random Omen chart from Liber Fanatica 7 for creepy foretellings about future events in the story.
What I really need now are some scary warhammerism variants on Magical Sight (probably would make a good article for Liber Fanatica 10). Realms of Soercery 2e had good ideas here that could be expanded upon.
