Homebrew Mechanic: Stress, Panic, & Affliction
Whether it’s a full campaign or a simple spooky oneoff adventure, eventually every DM is going to want to run some kind of horror scenario, at which point they’ll discover that there’s a lot more to delivering scares than just using assorted Halloween iconography. I’ve written before about creating an atmosphere of dread among your players using framing and narration, but I felt it was overdue to follow it up with a mechanical counterpart.
SAYING a monster/scenario is scary is all well and good, but if we turn fear into an actual gameplay system then we can use it to build out encounters and make our job as DMs easier. I also ended up making this system because I’ve read or adapted one too many modules involving “eldritch madness” that didn’t really understand how horror worked: adventuring is a tough business, and people getting overwhelmed with stress and panicking or lashing out is a way more grounded and useful expression of that than becoming mindless cultists because they saw a weird wet bug. Check over here for my history of how “madness” has been presented in TTRPGS, and how we can handle it better in the future.
Now for the system itself:
When a character is exposed to horrific, frightening, or unsettling circumstance, the DM may ask them to make a saving throw to avoid suffering a point of stress, represented by a dot or check penciled in near their proficiency marker. This can be anything from a con save to keep a strong stomach while rooting through the backrooms of a butcher shop, a wis save to reassure yourself that it really was just the wind making all that creepy noise in the abandoned manor, or a cha save to ward off the psychic interference of a aberrant mind-weapon. The DM may also rule that certain events automatically inflict stress, like seeing a trusted ally killed or getting swallowed by an eldritch horror.
A character can withstand a number of points of stress equal to their proficiency bonus. After which they’re considered to be at a “breaking point”. If any more stress is inflicted upon the character after that point the DM decides whether the character clears an amount of stress equal to their proficiency bonus and panics (the most likely option, gaining the frightened condition for 1d4, save ends) or gains an affliction comparable to the source of the stress (roll on the madness table, though find some better ones than the default DMG ones). The DM may also decide to have the stress compound, gaining an additional point but not having anything trigger, so that the tension breaks at the appropriate time.
Characters lose a point of stress by spending a full day resting in a haven (a safe place such as a town or a comfortable hidden hideaway) , though the DM may also rule that characters commiserating during a long rest (oh look at that, a reward for roleplaying) may lose a point of stress.
Using stress as a mechanic like this gives us something else to build encounters around other than just damage. We can have traps or one off random encounters during exploration that only serve to unnerve a few of our partymembers, softening them up to fall into panic when they encounter something actually scary. Imagine running a full haunted house dungeon where most of the encounters in the first half didn’t actually involve monsters, instead slowly building in tension as the party discovers the horrific truth of the ghost’s tragic past in hopes of putting it to rest.
