    Special Traits

    • Implant. The xill can use an action to implant up to 7 (2d6) xill eggs in one unconscious or incapacitated creature within 5 feet of it. The xill’s eggs hatch when the target takes its next long rest, at which point the young consume the host from within. After each long rest, the target must make a DC 15 Constitution saving throw. On a failed saving throw, the target gains one level of exhaustion. Xill eggs can be removed individually by the target or another creature by making a successful DC 15 Wisdom (Medicine) check. Each check deals 1d8 slashing damage to the target. The eggs can be destroyed by magic such as lesser restoration.


    • Multiattack. The xill makes one Bite attack, two Shortsword attacks, and two Claw attacks.
    • Shortswords. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage.
    • Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage, and the target must make a DC 13 Constitution saving throw or be paralyzed for 1 minute. A paralyzed creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.
    • Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage.
    • Longbow. Ranged Weapon Attack: +5 to hit, range 150/ft., one target. Hit: 7 (1d8 + 3) piercing damage.
    • Etherealness. The xill magically enters the Ethereal Plane from the Material Plane, or vice versa.


    Xills are the scourge of the Ethereal Plane, conquering everything in their paths with only one purpose: to perpetuate their race at the expense of others. All xills are female and capable of fertilizing their own eggs, but require living hosts to incubate these eggs, which they inject into paralyzed victims by means of a grotesque ovipositor normally kept retracted behind their mandibles. Evil and alien, the plane-shifting xills possess impressive intelligence and a totalitarian, militaristic culture all their own. Though they see most other life forms as incubators, they particularly prize phase spiders for this purpose.
