Damage. It is at the heart of rules for Dungeons & Dragons. Hit points are god. This is an excerpt from my forthcoming monograph, The Harrowed that expands on the variant rules for sanity, madness and lingering injuries in Chapter 9 of the Dungeon Master's Guide.

They are inspired by my favourite computer game, Darkest Dungeon. If you haven't played it, check it out. The rules for stress are particularly well thought out, adding an additional time pressure to complete adventures.

Variant: Stress

This variant is for gritty or low fantasy campaigns where adventuring life is not just hard on the body, but risks sanity as well.

When you encounter a stressful event you must make a Charisma saving throw or suffer psychic damage. If you fail your saving throw by 5 or less you also become Frightened for 1 minute. The DC and amount of damage depends on the difficulty of the stress: whether it is disturbing, shocking, horrifying or monstrous as per the Stressful Events table.

In low fantasy campaigns, where monsters (at least the non-human kind) are rare or legendary, encountering such creatures could be also a stressful event. See the following table:

CR Stress Difficulty
0-4 Disturbing
5-10 Shocking
11-15 Horrifying
16+ Monstrous

You get advantage on the Charisma saving throw if you have encountered this type of magical creature before. If you fail your saving throw by 5 or less you also become Frightened for 1 minute.

Stressful Events
Difficulty DC Damage Examples
Disturbing 15 1d4 Defeat in combat, witnessing a stranger take a severe wound or die, being trapped underground without light.
Shocking 17 1d8 Witnessing an ally take a severe wound or die, being betrayed by an ally, witnessing torture.
Horrifying 20 1d10 Witnessing an ally transform into a monstrous creature, a premonition of the end of the world, being tortured.
Monstrous 25 1d20 Encountering a god, being transported to hell, transforming into a monstrous creature.

Variant: Lingering Psychic Injuries

This variant gives an additional table for lingering injuries for psychic damage. Continue to roll on the old Lingering Injuries table for non-psychic damage.
