Stress system
Characters accumulate psychological stress from combat, horror, hunger, and hardship, and high stress produces breakdowns, debuffs, or mental afflictions. Darkest Dungeon's Stress is its defining mechanic — heroes crack under pressure, developing afflictions or, rarely, heroic virtues — turning the party's mental state into a resource as vital as health. Designers use stress systems to model psychological toll, to add a second attrition axis beyond HP (you can win a fight but lose a hero's mind), to force pacing and recovery decisions, and to generate emergent character drama. Key decisions: stress sources and accumulation rate, breakdown effects (debuffs, loss of control, party-wide stress contagion), recovery mechanics (town visits, camping, items) and their cost, and whether extreme stress can produce positive outcomes (Darkest Dungeon's virtues add hope to the dread). Pitfall: stress that only punishes, with no counterplay or recovery, becomes a grind of managing an inevitable decline; the system needs visible buildup, meaningful mitigation choices, and occasional upside so managing stress feels like strategy rather than watching characters unavoidably crumble.
