Dev Diary #31: A Stressful Situation

Hello everyone! I, Sean Hughes, come to you today with the long-awaited Dev Diary on how Stress works in Crusader Kings III! While the system is relatively straightforward, it does have some rather far-reaching ramifications for how characters choose to behave, so let us dive right in!


Stress is a representation of a character’s mental well-being. As characters accumulate Stress, they will increase up their Stress Level, with each level causing increasing penalties to their health and fertility values. The penalties at Stress Level 1 are fairly minor, but the penalties at Stress Level 3 can lead your character to an early grave!

The primary way that characters gain Stress is when the demands of the realm force them to take actions which go against their nature. For example, a Compassionate character will gain Stress for executing prisoners in the dungeon, even if those prisoners were traitorous rebels or, ahem… inconveniently positioned in the line of succession.

There are other sources of Stress too, though. Being locked up in the dungeon of another character will gradually increase Stress over time as the isolation and neglect take their toll on your psyche; other causes include overwork or the death of a loved one.

Regardless of the source, once a character accumulates enough Stress to pass a certain threshold and gain a Stress Level, they will suffer from a Mental Break.

Mental Breaks

Mental Breaks are a special kind of event which occurs when Stress overwhelms a character and compels them to do something — anything — to gain relief. Exactly what type of Mental Break a character has depends heavily on their personality traits, and each one gives the character several options for dealing with the situation they have found themselves in.

Not all Mental Breaks are equal, and the severity of the Mental Break will depend on your Stress Level when the event occurs. A Level 1 Mental Break may cause a Wrathful character to yell at one of their vassals in front of the whole court, insulting them and wounding their pride… but a Tier 3 Mental Break may instead drive that same character to murder their chosen heir in a fit of rage!

In addition to differing by Stress Level, some Mental Breaks are influenced by the situation you find yourself in. As an example, characters who find themselves locked up in a cell end up suffering from completely different Mental Breaks (often of greater severity), some of which can radically change their personality.

Regardless of the outcome, most Mental Breaks will give the character the chance to acquire a Coping Mechanism trait, which will help relieve stress and thus reduce the likelihood of having additional Mental Breaks in the future.

Coping Mechanisms

Coping Mechanisms are traits that represent the long-term methods characters have developed to deal with the Stress of their life. Most of them impose some form of minor penalty on a character’s skills, but in exchange they will enhance the potency of all forms of stress loss.

In addition to the passive effects of each trait, each one also enables a unique Decision characters can take to indulge in their vice and relieve a portion of their accumulated stress.

Regardless of the form it takes, all Coping Mechanisms are useful in one form or another. Having the ability to make Stressful decisions at-will is often far more useful than an extra point of Diplomacy or Stewardship, and each Coping Mechanism a character acquires makes it progressively easier for them to manage their Stress. It is expected that most rulers will acquire 1 or 2 Coping Mechanisms during their lifetime, though in some rare circumstances a character may end up with more.

Strategic Considerations

As developers, our goal with the Stress system is not to prohibit or punish players for taking certain actions, but rather to make them think twice about otherwise no-brainer decisions. Is it really worth it to execute that foreign claimant when doing so will give you 42 Stress? Maybe, but maybe not! That is a decision you will need to make when the time comes.

In this way, Stress also gives us another tool we can use to balance the various personality traits against each other. Some traits like Ambitious and Compassionate may have higher numerical bonuses, but they cause you to acquire Stress more frequently or in larger amounts. Others like Sadistic may make your vassals loathe you, but your character won’t be bothered by pesky concerns like morality when they have to do what needs to be done. Who knows… they might even enjoy it!

Regardless of what personality traits your character has, the optimal strategy with Stress is often not to avoid acquiring Stress at all costs, but rather to strategically acquire certain Coping Mechanisms and leverage them intelligently to keep your character’s Stress at ideal levels. Managing your character’s Stress well will ensure you are always able to take advantage of any opportunities that come your way, while behaving recklessly may leave you Stressed to the point of insanity during a crucial moment of your reign…

Anyway, that is all I have for you this week. I hope this has given you some insight into how the Stress system works in Crusader Kings III, and that this has inspired everyone to think of new and creative ways to leverage the system to its full potential!
