After looking at it a little more, it looks like a Mafia bug (the script asks for the "Effect" modifier, and Mafia returns the "Familiar Effect" modifier).
I'll see what I can do later, or I'll post a bug report so someone else can have a look.
Hey Slyz, I am really digging this script. I made a few modifications which you might be interested in:
1. Food/booze/spleen items now show adv/fullness (or adv/drunk or adv/spleen)
2. To save space, adventure and statgain averages are shown instead of ranges (e.g., 8-11 shows 9.5 instead, 10-12 shows 11.0 instead). It's easy to tell when this has been done because an averaged quantity will always have a decimal place.
