The gauge that ends more runs than hit points
Stress runs 0 to 200. The number that matters is where the thresholds sit:
- At 100 stress: the hero’s resolve is tested. They become Afflicted (the usual outcome) or, on a small chance, Virtuous. Either way they are now locked into that state until they leave the dungeon.
- At 200 stress: a heart attack — the hero hits Death’s Door, or dies outright if already there.
Stress is not fully healed after a mission (it caps at 100 in town), so it carries between runs. This is why more expeditions fail to a heart attack than to HP loss.
Virtue chance is a formula, not a roll you can steer
When a hero hits 100 stress, the chance they turn Virtuous instead of Afflicted is:
- Base 25% at equal resolve level to the dungeon.
- −5% per level the hero is below the dungeon’s level.
- −33% if the gap is 6 (a level-0 hero in the Darkest Dungeon location).
- Floor 1%, hard cap 95%.
- Trinkets can add up to +45% (e.g. Irrepressible Quirk +5%, Hero’s Ring +25%, Ancestor’s Tentacle Idol +20%), for a practical ceiling around 75%.
A Virtuous hero drops to 45 stress, heals a little party stress, and gains one of five buffs (all also grant +25% Stun/Blight/Bleed/Disease/Debuff/Move resist):
| Virtue | Bonus | Start-of-turn act-out |
|---|---|---|
| Stalwart | +15% PROT, +8% Death Blow Resist | 25%: self stress −15 |
| Courageous | −33% stress taken, +2 SPD | 25%: allies’ stress −4 |
| Focused | +10 ACC, +8% CRIT | 25%: one ally +10 ACC, +10% CRIT |
| Powerful | +25% DMG | 25%: allies +15% DMG |
| Vigorous | +4 SPD, +10% DODGE | 25%: self heal 10% max HP |
The key truth: affliction is the default and it is random. You cannot plan which hero breaks or when. You only control the input — keeping stress under 100 in the first place.
The light table (the stress axis)
Light starts at 100 and drains as you explore: 1 point per known segment, 6 per new area (more on Stygian/Bloodmoon). Higher light means less stress and more scouting; lower light means more danger but more loot. Raising light costs 1 Torch per step (left-click the meter).
Using Radiant difficulty as the baseline, stress taken climbs as light falls:
| Light | Stress taken | Also |
|---|---|---|
| Radiant (76–100) | floor (lowest) | +15% scouting, +25% monsters surprised |
| Dim (51–75) | +10% | — |
| Shadowy (26–50) | +20% | — |
| Dark (1–25) | +30% | +10 monster ACC/DMG, +3% monster crit |
| Black as Pitch (0) | +40% | +40% monster DMG, +5% monster crit, +40% heroes surprised, up to 95% extra loot |
Read it as a dial: bright torch for safe farming, dark for loot runs you can handle. Note the 80% cap — no combination of trinkets and skills can cut stress taken by more than 80%.
How to actually heal stress
- Abbey and Tavern (town): the big heals, but cost gold and hold the hero for a week. This is where afflicted heroes get cured.
- Idle in the estate: 5 stress/week, or 15/week with the Puppet Theatre district.
- Camping skills: Encourage and Pep Talk (learned by every hero except the Flagellant) heal and buff stress reduction.
- In combat: the Jester’s Inspiring Tune is the party-wide stress heal to build around. Killing an enemy has a 50% chance to heal the killer 3 stress; a critical hit heals 3 and can splash to allies.
Decision rules
- Keep torch high when you cannot afford a bad event.
- Bring a Jester on any delve longer than a couple of fights.
- Camp before a boss to drop the party average.
- Retreat before 200 — a Virtuous hero is safe at 200, an Afflicted one is not.
- Rotate stressed heroes through the Abbey/Tavern; do not send a 100+ hero back in.
