ブレインチャイルド Brainchild

A rumor can become so vivid and so persistent that it comes to life, creating a brainchild—a living illusion that hatches from an intense belief in a remorseless and implacable killer. Often, these rumors swirl around the victims of a phantasmal killer spell. A brainchild's capabilities grow when they pursue a believer but deflate against skeptics, making them only as bad as one thinks they are. A simple drive to stalk, terrify, and kill propels a brainchild, but the creature might also exhibit other behaviors ascribed to them through gossip.

Universal Language／Universal Language Anything spoken by the brainchild is perceived by the listener in its native language.
Urban Legend／Urban Legend A brainchild is sustained only by the reputation that precedes them. Mindlesscreatures are immune to a brainchild and can't perceive them. The brainchild's size, features, and items, as well as the appearance of their attacks, match what the foes perceiving them expect. If foes expect to see different things, the brainchild chooses which to manifest. If any creature that can perceive the brainchild believes the brainchild has one of the abilities below, the brainchild has that ability. A creature can Seekor Sense Motive (against the brainchild's Deception DC) to attempt to disbelieve an individual ability. If at any point no creature perceiving the brainchild believes in the ability, the brainchild loses that ability immediately. If foes expect different particulars, such as one believing the brainchild is immune to fire and another believing they're immune to divinations, the brainchild chooses one to have.

助言とルール：Spreading Rumors Spreading Rumors

Brainchildren require setup. Create some rumors the PCs might hear around town, adding more if they Gather Information . Take note of what rumors they share and who believes which ones. Don't include too many—if the PCs believe them all, the brainchild will be too powerful! Examples include “I hear the Beast of Chimney Hill can walk through a fire unburnt” and “Woke with a pounding headache. Old Selby's Dog must be lurking about again.”
