Publisher's blurb: Call of Cthulhu is a game of cosmic horror where intrepid investigators pit themselves against entities and powers that literally shred the fragile sanity of the mere humans who face them. Tracking an investigator’s sanity is straightforward enough using the standard investigator character sheets. However, this does not track the cumulative number of Sanity points lost to any specific entity or situation the investigators may encounter, which has an upper limit dependant upon the horror in question. Therefore to make this tracking easier this supplement has Sanity Tracker sheets intended to simplify recording the loss of sanity to any given type of Mythos entity or horrific situation.
