Mike’s Hierarchy of Terror d20™

by lee-a-michael@comcast.net

(the following replaces the sections Temporary Insanity & Indefinite Insanity. These house rules provide an alternate system for determining the effect of Sanity loss upon an investigator. This system focuses more upon the accumulated and compounding effect of terror. It is intended to simulate a decent into madness through attrition.)

Starting Sanity

A Characters starting Sanity is equal to the characters Wisdom score. This score represents a starting characters current sanity points, as well as the upper limit of Sanity that can be restored by the Psychoanalysis skill. After creation, a characters current sanity score often fluctuates considerably and might never again match starting Sanity. A change in a characters Wisdom score changes the starting Sanity score in regard to what Psychoanalysis can restore. Current Sanity, however, does not change if Wisdom rises or falls.

Maximum Sanity

The Cthulhu Mythos Score skill simulates character comprehension of aspects of the Mythos. Once gained this horrible knowledge is never forgotten, and the character consequently surrenders mental equilibrium. An investigator’s Sanity weakens as the comprehension of the mythos increases. Such is the way of the universe. An investigator’s current sanity points can never be higher than 19 minus the ranks the character has in the Cthulhu Mythos skill. This number is the character’s maximum Sanity.

Current Sanity

Making a Sanity check: When an investigator encounters a gruesome, unnatural, frightening, or supernatural situation the GM may require a player to make a Sanity check with a d20. The check succeeds if the result is equal to or less than the characters Sanity. On a successful check, the character either looses no Sanity loss or only a minimum amount. Potential Sanity loss is usually shown as two numbers or dice rolls separated by a slash, such as 0/1d4. the number before the slash indicates the number of Sanity points lost if the check succeeds (in this case none): the number after the slash indicates the number of Sanity points lost if the Sanity check fails (in this case between 1 and 4 points). A investigators current Sanity is also at risk when the the character reads certain books, learns spells contained within, and attempts to cast them. These losses are usually automatic (no Sanity check is involved)- the character who chooses to undertake that activity forfeits the required Sanity points. See the Magic chapter for details.For the most part a new Sanity-shaking experience requires a new Sanity check. However the GM always gets to decide when characters make Sanity checks. Seeing several horribly mangled corpses at one time or in quick succession may call for just one Sanity check, while the same encounters at intervals of several hours may require separate checks. Loosing it: Any time an investigator looses any amount of Sanity points from a single roll, he or she has suffered enough shock that the keeper must test Sanity, and ask for an intelligence check DC 10: if the roll succeeds, then the Investigator realizes the full significance of what was beheld, and Looses It. An investigator who Looses It must check on the table below to find the number that equals their current Terror. If the Intelligence check fails, then the investigator does not Loose It, but the sanity points lost accumulate into the

Terror Pool.

The Terror is a pool made up of all the lost Sanity accumulated by an Investigator during the course of an adventure. Each time an Investigator loses Sanity it goes to the Terror Pool where it accumulates so that each time the investigator is tested, the effects of Loosing It is greater and greater. It matters not if the Sanity loss is caused by one event or several successive events, the investigator Looses It as determined by the table below. The accumulation continues until the Keeper determines that all the aggravating factors have been alleviated at which point the Terror Pool goes back to 0. At the Keepers option, accumulations in the Terror Pool may be reapplied even after the fading of the aggravating factor if the factors are close enough in nature to warrant it (i.e. faced with the same situation all over again).
