I'm currently adding wandering monsters to the module I'm developing. They are basically "invisible" icons that roam the map and trigger a convo if they happen to collide with the PC. There are also visible monsters wandering around the map which I'm handling slightly differently (they chase etc), so the wandering monsters are there just to add an unpredictable element of danger.
I was wondering if it is possible/how to add a chance factor to a convo option? Ie, when the PC triggers a wandering monster convo I'd like to offer a "flee" option, but for it to have a random chance of success (say 60% or something) with failure triggering the combat. I have a feeling this should be possible but I can't quite see how. If this can't be done I might link it to a character trait/skill instead, so its no massive problem (ideally I'd want to do that anyway, to adjust the % chance - eg, it decreases if the PC has the "evade" skill or something similar).
thanks!
