Traits

Spider Climb. The spider can climb difficult surfaces, including along ceilings, without needing to make an ability check.

Actions

Multiattack.

The spider makes two Bite attacks.

Bite.

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) piercing damage plus 10 (3d6) poison damage.

Blood Web (Recharge 5–6).

Ranged Weapon Attack: +7 to hit, range 20/60 ft., one creature. Hit: The target is restrained by blood‑soaked webbing.

A restrained creature can use its action to make a DC 16 Strength check, breaking free on a success.

The webbing can also be attacked and destroyed (AC 12; hp 10; vulnerability to fire; immunity to bludgeoning, poison, and psychic damage).

Blood Web (Ex) A bloodsilk spider can throw a blood-red web eight times per day. This is similar to an attack with a net but has a maximum range of 50 feet, with a range increment of 10 feet, and affects targets of up to Medium size. The web anchors the target, allowing no movement. Attempts to escape or burst the webbing gain a +5 bonus if the trapped creature has solid leverage while pulling free. An entangled creature can escape the web with a DC 13 Escape Artist check or a DC 17 Strength check. Each 5-foot section of web has 12 hit points, hardness 0, and damage reduction 5/—. The blood-soaked web is immune to fire. Skills A bloodsilk spider can always choose to take 10 on Climb checks, even if rushed or threatened.

 

 
Bonus Actions

Blood Drain.

As a bonus action, the spider commands its blood‑infused webs to burrow into restrained victims. Each creature restrained by one of the spider’s blood webs loses 10 (3d6) hit points, and the spider gains temporary hit points equal to the total damage dealt.

If a creature is reduced to 0 hit points by this effect, the spider immediately recharges Blood Web.

Reactions

Silken Recoil.

When a creature the spider can see misses it with an attack, the spider moves up to 10 feet without provoking opportunity attacks.

Description

Bloodsilk Spiders are nightmarish predators born from the deepest fissures of the Demonweb Pits, where Lolth’s cruelty seeps into every strand of webbing. Their bodies swell to the size of a small horse, their chitin lacquered in a glossy crimson sheen that pulses faintly like living flesh. Thick, rope‑like strands of blood‑infused silk drip from their spinnerets, each thread twitching with a parasitic hunger of its own.

These spiders do not merely ensnare prey—they feed through their webs, driving needle‑thin filaments into flesh to siphon blood directly into their swollen abdomens. When a victim struggles, the webbing tightens and burrows deeper, drinking faster, while the spider’s carapace darkens with fresh nourishment.

Bloodsilk Spiders are disturbingly intelligent in their hunting patterns despite their low cunning. They stalk from the shadows, clinging to cavern ceilings or Demonweb bridges, waiting for the perfect moment to strike. Their webs form pulsating lattices that resemble veins more than silk, and entire caverns can throb with the rhythmic pulse of their collective feeding.

Drow cultists sometimes cultivate these horrors as guardians, but even they treat the creatures with fear. A Bloodsilk Spider that has fed well becomes swollen, jittering with stolen vitality, and its movements blur with unnatural speed. In the Demonweb Pits, such spiders are said to be the “favored children” of Lolth—creatures that embody her appetite for suffering, entrapment, and slow, exquisite death.
