Mechanical question – I’ve been thinking about a magic bow – one that hits a terrible hit on every target (maybe messy, best damage of 3 rolls?) but negatively effects the party. I want the devastating efficiency of this bow to bring everyone down, to make them feel demoralized and hopeless at all the killing.
Is there a mechanism where I could say, “Damage b[3d6], the following two rolls by other PCs take -2”? This would create an interesting dynamic where the archer would love this bow but the party would be begging them to stop using it. Kind of a cool corrupting mechanic!
