Special Traits

  • Antimagic Susceptibility. The snake is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the snake must succeed on a Constitution saving throw against the caster’s spell save DC or return to the textile to which it is bound for 1 minute.
  • Construct Nature. The thread-bound construct doesn’t require air, food, drink, or sleep.
  • Immutable Form. The snake is immune to any spell or effect that would alter its form.
  • Magic Weapons. The snake’s weapon attacks are magical.
  • Shifting Form. The snake can enter a hostile creature’s space and stop there. It can move through a space as narrow as 1 inch wide without squeezing.

Actions

  • Constrict. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 13 (2d8 + 4) bludgeoning damage and the creature is grappled (escape DC 16). Until this grapple ends, the creature is restrained, and the snake can’t constrict another target. Only a beast or monstrosity can be made into a thread-bound construct. To create one, a spellcaster ritually sacrifices a living creature over a textile’s materials. The creator must then meditate over the newly woven textile for a week, setting the conditions that trigger the creature, like the conditions in the glyph of warding spell. When a creature becomes a thread-bound construct, it retains all its statistics except as noted below.

About

Found on tapestries and rugs, thread-bound constructs are created with magic that infuses textiles with the essence of a once-living creature. They appear mundane until triggered, at which point the pattern comes to life.

Thread-Bound. When killed, the creature vanishes, reappearing upon the textile to which it is bound in a death pose. At the next dawn, it again assumes its living pattern and can be triggered again. If the textile is destroyed while the pattern of the creature is on it, the creature is also destroyed. Otherwise, damage to the textile does not harm the creature. If the creature is killed and the textile has been destroyed, the creature is permanently destroyed.
