No Clue If This Is A Real Scenario That Could Take Place I've Only Heard About Eureka Secondhand - Blog Posts

If I were just one degree bolder as a designer and the Eureka: Investigative Urban Fantasy rulebook wasn’t already too big I would implement a rule where your investigator has to go to the bathroom once per 10 or 20 Ticks or else lose Composure or something.

What this would add to the game is something that occasionally separates one investigator at a time from the others thus making them vulnerable, and a plausibly-deniable-through-mechanics excuse for one investigator to separate from the others on purpose in case there’s some secret they have to keep, and it would start to be noticeably weird that certain investigators (like vampires) never use the bathroom; what it would also add to the game is pissing and shitting mechanics.
