This is what i can find in the script (other than various dialogue bits associated with wearing it)Can someone please tell me the effect of dressing a slave with a Karada?
I wasn't able to find any information searching the thread and in the wiki neither.....
* generic effect from wearing harness or being naked:
if corruption is less than 30, perverted trait at no more than 50: humiliation +2, happiness -1
* for a girl with Shamefast trait, effect from wearing harness or being naked:
if corruption is less than 40: affection -1, humiliation +1, happiness -1, willpower -1 (dice roll)
* for a girl with Vanilla trait, effect from wearing harness:
happiness -1, stress +1, humiliation +1
If humiliation is at 15+ this translates to losing a point of willpower (and humiliation is reduced to 8) so that's an indirect way of affecting it, i guess.
