Understands Sylvan but cannot speak. Challenge 1 (200 XP) Numbing Mucus. The Alp-luachra excretes a numbing mucus that prevents its host from feeling its presence inside its body. The host has disadvantage on all checks to determine the presence of the Alp-luachra.

Salt Vulnerability. The host of the Alp-luachra can ingest a half pound of salt to incapacitate the Alp-luachra for 1d4 hours. If the Alp-luachra is incapacitated in this manner, the host must make a DC 12 Constitution saving throw or suffer the Poisoned condition for 24 hours.

Actions Poisonous Bite. Melee Weapon Attack: +4 to hit, reach 5ft., one creature. Hit 4 (1d4 + 2) piercing damage, and the target must make a DC 13 Constitution saving throw, taking 6 (2d6) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but Poisoned for 1 hour, even after regaining hit points, and is Paralyzed while Poisoned in this way. The Alp-luachra cannot take this action while it is inside a host.

Parasitic Implant. The Alp-luachra takes a full round, from the start of its current turn to the beginning of its next turn, to crawl into the mouth of an unconscious or paralyzed creature no size greater than Large. Once inside the creature’s body it expands to fill the esophagus of the creature, leaving a small hole for air to pass through. The host is considered possessed by the Alp-luachra, though the Alp-luachra does not exert control over its host’s actions or thoughts.

Once the Alp-luachra has implanted itself in its host’s body, whenever the affected creature attempts to eat or drink, including magical or poisonous substances, the Alp-luachra consumes the substance instead. The host creature begins to suffer from the lack of food and water as described on page 185 of the Player’s Handbook, and cannot benefit from or be harmed by any ingested substance.

A creature can stall the effects each day by consuming twice the normal amount of food and water and passing a DC 15 Constitution save. This save can only be done once per day at midnight, prevents starvation and thirst from progressing for only one day, and does not reset the count of days to zero.

While inside the host’s body, the Alp-luachra cannot be targeted by attacks and has advantage on all saving throws. It does not benefit from advantage on saving throws if it is incapacitated by any means. If its host dies, it emerges from the corpse within 1d8 hours to seek out a new host.

The Alp-luachra can be detected by the detect evil and good spell and the detect poison and disease spell, or any spell that would allow a creature to locate another. A creature can also perform a contested check, their Heal check versus the Alp-luachra’s Stealth check, to detect Alp-luachra’s presence.

Once detected, the Alp-luachra can be removed by pulling it out of the esophagus. This can be accomplished in two ways. The Alp-luachra can either be killed by damaging effects, or a creature can remove the Alp-luachra by making a successful Heal check opposed by the Alp-luachra’s Constitution save. If the Heal check fails, the host takes 1d6 slashing damage and the Alp-luachra is not removed. The Alp-luachra has disadvantage on its Constitution save if it is incapacitated by any means.

Asphyxiation. The Alp-luachra can use its action to close the airway of its host, causing the host to suffocate. It can reopen the airway as a free action.
