Is it possible to have a random speech challenge difficulty in a topic? I know you can select the difficulty in the Geck but i dont recall a random selection (im at work atm).

Also, is there possible to scale the speech/barter challenge for returning topics? For exemple, a player ask for a discount for medical help, next time it will be harder...

You could set "GetRandomPercent <=25" as one of the conditions,
Then "GetRandomPercent <= 50" as another one which will have a higher skill requirement.

That is, if GetRandomPercent allows <= 25 and <= 50 to overlap

Of course! silly me. I gonna give it a try tonight at home. Adding a few conditions of different level in my topics... Thanks for the tips!
