This is my attempt to grow on this issue in Warhammer Fantasy Roleplay 2nd Edition. This is also my submission to the Three Page Fiction Contest over on /r/WarhammerFantasyRPG!
I hope you enjoy Ruinous Reactions!
Ruinous Reactions is an overhaul for Fear, Terror, and Insanity in WFRP2e, because a) being frozen isn't fun game play, and removes player agency, and b) RPGs tend to have a very ableist view of mental health. This new system intends to fix both of these issues, and turn Fear, Terror, and Insanity into interesting game play opportunities, rather than agency sucking moments!
Edit: As a side note, between this post and the last, versamus reached 100,000 views, and this post was actually our 200th! Lots of milestones for the new year!
