Memory Theft (Su) A creature that takes damage from a mementor’s claws must succeed at a DC 21 Will save or suffer memory loss that takes the form of a cumulative –1 penalty to Intelligence-, Wisdom-, and Charisma-based ability checks and skill checks, as well as to the DCs of spells and special abilities based on those ability scores. If this penalty ever reduces a spellcaster’s key ability score modifier to +0 or lower, the spellcaster can no longer cast their highest level of spells. When the penalty reduces a creature’s ability modifier in any affected ability score to –5, the creature is immediately affected as if by the feeblemind spell. A creature that doesn’t arrive at the feeblemind stage can recover from the penalty as if each –1 increment were a temporary negative level. The restoration spell works on each –1 increment as if it were a permanent negative level, but psychic surgery can cure the entire penalty at once. Mindless creatures are immune to this effect.


Environment any (Shadow Plane)
Organization solitary or convocation (2–4)

Skeletally slim, a mementor is like a humanoid mantis with chitin of various hues. The creature also has mantis-like wings, which it drones, shimmers, and vibrates in specific patterns to create its confusion spell-like ability, and which it snaps to create its greater synaptic pulse.

Mementors are fey embodiments of the horrors of memory loss. They consume memories, causing lasting amnesia in their victims. Such prey can end up in a permanent state of infantile wonder, fear, or bewilderment. Though fey, mementors are native to the Shadow Plane. Some scholars believe they manifested from a fear of or rage at being forgotten. Unscrupulous corporations and governments employ mementors as memory assassins to wipe knowledge from targets without killing them. Mementors of this sort often work with a team of mortal mercenaries.

A mementor stands 6 feet tall but weighs just 100 pounds.
