An Improvement token is a token that the player may gain through the resolution of certain Encounters, Spells, Conditions, or other effects. It can allow the player to gain more dice when they resolve skill tests that match the improvement token.

If the player gains an improvement token, they take the token and place it on their investigator card with the "+1" side facing up. If they improve it again, flip the token to the "+2" side. This counts as part of the base skill, so it will stack with bonuses from an Item or other source.

The maximum a skill may be improved is twice. Any further improvements are ignored. It is possible to improve all five of an investigator's skill if it happens in a game. Improvement tokens may always be applied to any test unless specifically told otherwise: Resistance will never affect Improvement tokens.

If Lily Chen improves a skill, she may immediately improve the same skill again once a round. If Joe Diamond improves a skill, he may immediately improve a different skill at the same time once per round. Harvey Walters can undertake an action to improve another investigator's skill if that skill is lower than Harvey's. If Sefina Rousseau rolls two or more successes during a skill check, she may spend a Focus to improve that skill.

A Location Encounter in San Francisco is likely to improve Observation. Encounters in Shanghai are likely to improve Lore. Sydney will likely improve Strength, Rome will likely improve Will, and Istanbul will probably improve Influence.


Under the Pyramids included the possibility of impairing a skill, which would reduce the number of dice a player gets for performing a skill check. Just like improvements, they may be impaired a maximum of twice per skill. If Calvin Wright gains an Impairment, he may choose to instead recover 1 Health and 1 Sanity.

Improvements and impairments cancel each other out.
