I've started a new Warhammer Fantasy campaign taking the Witch's Song as my groups first adventure. We've played for four sessions/nights now and although I really love the combat mechanics, the best thing about 3rd are the social dynamics this game offers (both in and especially out of combat). Add the mumbling dove-enthousiast of the Witch's Song and you have a great game.
One thing that does not quite work for me is the appearance of chaos starts in rolls. The module we play is full of things that happen when the players roll one, action cards have these effects and so on…but the only way to roll a chaos star is when purple dice are added to a check and that rarely happens. I tried adding a standard purple die to all checks while navigating the swamp and although that gave some fun bits, it also made it almost impossible for my poor players to succeed at basic tasks.
So my question is: am I missing someting? Is there another way to get chaos stars on rolls? Or is it normal to add at least one purple die to any check? How do you handle this?
Thanks for any thoughts.
