Stress and Echoes

DM's note, these are the mechanics for stress as referenced in the Storm Isles campaign. Sources of stress and their effects can and likely will be different for other settings.


Stress increases the longer the party remains in the dungeon, experiencing it's horrors, and being exposed to the psychic drone of the Sliver hive.
Stress increases from 0 – 100 before a party member has their resolve tested. A percentile die is rolled, 70%+ results in a Valorous result, 69% and below results in a mental affliction. Virtues and Afflictions end upon exiting the dungeon and resting for an amount of time.

Long resting:

  • 1 – 25; DC 8 Con save to long rest. Echo on failure.
  • 26 – 50; DC 10 Con save to long rest. Echo on failure.
  • 51 – 75; DC 12 Con save to long rest. Echo on failure.
  • 76 – 99; DC 14 Con save to long rest. Echo on failure.

If an adventurer loops back around to 200 stress, they become catatonic.


  • Courageous(1) – Reduce own stress to 50, Halves the stress gain of the entire party; In combat, cannot be frightened or charmed.
  • Stalwart(2) – Reduce stress to 0, improves chances of virtue of others to 50%+; In Combat, can have undying resilience once per day.
  • Tenacious(3) – Reduce stress to 50, advantage on Strength and Dexterity saves; In Combat – Gain 5 temp HP for defeating an enemy, does not stack.
  • Wise(4) – Reduce stress to 50, advantage on Wisdom and Charisma saves; Once per combat, grant an ally advantage for one roll, free action.



  • Paranoid(1) – Can be flanked by allies, DC 16 Wis save when long-resting or take additional stress damage.
  • Psychotic(2) – DC 15 Wisdom Save or lash out when being healed, Failing save during an Echo doubles stress gain for all.
  • Traumatized(3) – DC 12 Wisdom Save or become Frightened, DC 16 Wis save when long-resting or gain a level of exhaustion.
  • Sadistic(4) – DC 15 Wisdom save, when wounded, lash out at closest ally. Gain 5 temp HP for doing so, does not stack.
