Rapping Spirit CR 1
Rapping spirits are unquiet dead with just enough substance to produce cacophonous knocking and loud bumps in the night. Adventurers can attempt communication with these intelligent spirits by working out codes to form cryptic messages at the rate of 1d10 words per minute with a successful Linguistics check.
CR 1; XP 400; Alignment varies persistent haunt (5-ft. radius)
Caster Level 1st; Notice Perception DC 10 (to hear faint knockings on walls, floor, and furniture)
hp 4; Weakness tricked by hide from undead; Trigger proximity; Reset 1 day
When this haunt is triggered, a chorus of agitated raps and blows rings out from nearby hard surfaces (those capable of physical manipulations, as mage hand) as unquiet spirits convey their unrest to the living. All who hear the supernatural knocks are affected by cause fear (save DC 11).
Rapping spirits typically ask for their mortal remains to be laid to rest or for the PCs to seek revenge for their deaths. Fulfilling these requests dismisses the haunts.
