Yuan-ti Anathema

Yuan-ti Anathema

Harper Field Dossier
Combat reference
Type	The pinnacle of yuan-ti transformation — a great serpent body with arms and many snake heads
Vulnerabilities	Silence. Every working it knows is spoken; struck mute, it is only teeth and coils. Cold, force, and honest steel all bite in full
Resistances	Fire and lightning
Immunities	Poison and thunder — venom means nothing to it, though its body can still be fouled and sickened (the poisoned condition took hold at the bridge)
Condition Immunities
Strong Saves	Magic slides off it — it shrugs at spells and magical effects that lesser creatures fail against
Senses	Reads the warmth of living bodies through the heat-pits below its eyes; darkness is no refuge from it
Movement	Swims as swiftly as it slithers, and will come up out of a river you thought was empty
Notable Abilities	A druid's grasp of vines and grasping earth — all of it spoken aloud; many biting heads and crushing coils within reach of its arms
Provenance
Knowledge	Partial
First Encountered	Session 54, rising from the Winding Water at Boareskyr Bridge
Filed by	Agent Wren, of the Tellstone circle

The Harpers' Read

An anathema is what a yuan-ti spends a lifetime of rites trying to become, and the hills keep very few of them — the bridge-keeper at Boareskyr had twenty years of books and had never once written one down. Treat every report of one as true until proven otherwise.

Your first move is not a blade. It is Silence. Everything the creature casts, it speaks, and a single well-placed hush strips it down to an animal — a big one, with many mouths, but an animal. After that, mind your elements: it bathes in fire and lightning without much complaint, and poison is a joke to it, but cold, force, and plain sharpened steel wound it honestly. Do not count on your spells landing at all — magic slides off the thing, so bring effects that give no save or allies who don't cast. Keep your distance while it dies; every one of those heads bites, and the arms are strong enough to crush. And do not bother hiding in the dark — it reads your body's warmth through the pits beneath its eyes. The company at Boareskyr Bridge killed theirs without taking a single blow, and that is the correct number of blows to take from an anathema.

Encounters of Record

• Session 54 — An anathema swam down the Winding Water to Boareskyr Bridge behind its clutch of spies and came ashore in front of the whole town. Karma bent its Entangle aside, Gootcha's Silence deleted its entire spell list, Baelgrum's Commanded it through a wolf pack, and Keyleth's longbow finished it before it ever completed an attack. The carcass was harvested in the street.
