Best ForGroups who want clue-driven horror with ordinary investigators and lasting consequences. Suits focused mysteries and campaigns where survival matters more than defeating every threat.Groups who want dark, gritty fantasy where ordinary people face extraordinary dangers in a richly detailed setting. The career system creates unique character arcs from rat catcher to witch hunter.
HighlightsPushing a failed roll offers another chance at the goal with a more serious consequence if it fails. Learning Mythos lore reduces maximum Sanity, tying useful knowledge to lasting vulnerability. An Idea roll gets a stalled investigation moving again, with failure putting investigators into danger.The career system structures advancement around trades, moving a character through jobs that shape both skills and story. Success Levels measure how far a d100 test beats or misses its target, turning every roll into a degree of result. Advantage accumulates during a fight, rewarding momentum with stacking bonuses to attack tests.
ConsiderationsA major wound can leave an investigator dying, making direct confrontation dangerous. Bouts of madness temporarily place investigator actions under Keeper control. Foot and vehicle chases track relative speed and movement actions, adding a separate procedure to pursuit scenes.The rules assume the Old World setting, so moving WFRP elsewhere means reworking its careers and tone. Comparing tens digits for Success Levels on every test adds a math step that can slow combat. Advancement is career-gated, so a character often must finish or leave a career before branching into new skills.
