Skein — The Parasite

Look: Dog-sized translucent spider knotted from twisting threads; too many independently moving legs and six tendrils buried in Bren's skull. Vibe: A furtive, controlling feeder; terrified of Xarrul and willing to hurt its host to preserve its hiding place.

  • Exists only in the Ethereal Plane; seeing it does not allow cross-planar attacks
  • Uses Bren as senses, voice, shield, and food; Bren remains conscious throughout
  • Xarrul's proximity distracts it, creating Bren's deepest lucid windows
  • At 10 HP or less, flees and tears free; prevent escape for a permanent rescue

STR DEX CON INT WIS CHA AC HP Move
-2 +3 +2 +2 +3 -1 13 38 30 ft., climb 30 ft.

Saves/skills: WIS/DEX +5, Stealth +7, Perception +5 Resist: psychic; nonmagical bludgeoning/piercing/slashing. Immune: charmed, frightened. Senses: blindsight 30 ft. through host, darkvision 60 ft., passive 15.

Traits

  • Parasitic Bond. Sees/hears/speaks through Bren; overrides his actions without a save.
  • Six Tendrils. Each AC 13, 5 HP, Ethereal-only target. Each severed = loses host control 1 round; all six = Bren free 1d4 hours. Regrow in 1d4 hours.
  • Mind Drain. Long-term WIS loss; killing Skein restores Bren only to WIS 10.

Actions / Reaction

  • Psychic Lash. +5 to hit, 30 ft., Ethereal target that perceives it; 10 (3d6) psychic.
  • Suppress Host. Force or prevent one of Bren's actions; no save.
  • Flee (1/day, ≤10 HP). Detach, double speed; Bren takes 7 (2d6) psychic and is stunned 1 round.
  • Silence the Host (reaction). Bren tries to reveal protected information: DC 15 WIS at -2; fail = garbled words or pain, success = one clear sentence.
