Big Spiders, also known as Wolf Spiders, are large, fast creatures with many legs and spiny backs. They are both predator and prey, and are found in dimly lit regions. Their bite is highly lethal.


Big Spiders resemble arachnids, with black bodies, eight legs, and several quill-like spines protruding from their bodies. These spines, and their fangs, fade into a brown coloration. Big Spiders' colors are affected by room darkness.



A Big Spider attacking Hunter

Big Spiders can be killed with a single Spear, but can leap over thrown objects in their line of sight. They are unable to dodge thrown objects mid-lunge. Big Spiders, like all other arthropod-like creatures, can be poisoned and killed by a Spore Puff. Additionally, Flashbangs kill Big Spiders.


Big Spiders have a large range of vision, making it difficult to go undetected. Like all other creatures, crouching and crawling makes it less likely for Big Spiders to notice Slugcat. Big Spiders are able to hear. Rocks can be used to interest them. Additionally, Big Spiders may be distracted by other prey, such as Lantern Mice or Scavengers, which they are more interested in than Slugcat.


Due to their cyclical fear of light; avoidance of Slugcat when holding a Lantern or Spear; and spawning in a small amount of regions, Big Spiders do not pose a large threat in campaign. Their lunges are slow and inaccurate, and can be jumped over or ducked beneath.

Abilities & Behavior


Big Spiders are initially afraid of prey when seeing them for the first time, triggering a 7.5 second timer before their default aggression is applied. These timers can run simultaneously and do not interrupt each other. If a Big Spider forgets the prey it's tracking, which happens anywhere between 7.5 second and 45 seconds, the fear timer re-triggers.

Big Spiders shift between aggression and fear towards creatures holding a Lantern, Slugcat if they have eaten a Neuron Fly, and Lantern Mice. The duration of each phase and its intensity depends on the darkness of the given room. The darker a room is, the more frightened of light Big Spiders become. In a fully dark room, their ShyFromLight cycle is at its longest, spending roughly 10 seconds in one phase before switching to the other, while lighter rooms result in shorter and weaker durations of fear. It does not apply to unheld Lanterns, Lanterns that are a part of a background prop, Slugcat holding a Lantern Mouse, or room lighting. The ShyFromLight cycle runs independent to default relationships, and only takes priority when a Lantern becomes held.

When in groups, the Big Spider with the highest dominance is likely to share its ShyFromLight cycle with other Big Spiders in sight.

Grabbing & Clinging

Big Spiders possess two types of attack; a grab and a cling. When grabbing, they have a short windup and produce a rustling sound before leaping at their target. Two fangs display during a lunge attack, and are visible even in dark rooms. Although this attack has a 50% chance of lethality, Slugcat is never able to escape a Big Spider's grasp on their own, due to Big Spider bites having a stunbonus of 60, higher than the required <30 to retaliate with a weapon.

Their cling attack is a non-lethal, non-stunning attack that only slows Slugcat and other creatures down. Big Spiders are less likely to cling to Slugcat if they are holding a Lantern or Spear, or if they have neuron glow.

In groups, Big Spiders pose a larger threat against both creatures and Slugcat.

Big Spiders keep track of other Big Spiders that they see. When not actively pursuing prey, they seek out dead Big Spiders, biting and temporarily reviving them. Revived Big Spiders attempt to return to their dens. After roughly 20 seconds, they die again, but can be re-revived. Big Spiders can also revive Spitter Spiders, which takes slightly longer. They do not attempt to revive ✔️DLC Mother Spiders. Big Spiders and Spitter Spiders cannot be revived if killed by Spore Puffs, Flashbangs, if drowned, if below -8 health, or if fully eaten by a carnivorous Slugcat. If the player kills a Big Spider, they receive its kill credit, even if the Big Spider is revived. Killing a revived Big Spider again does not yield another kill credit.

Wall Crawl

Big Spiders are able to crawl along background walls. However, they prefer climbing along walls and poles to hunt their prey.

Variants & Attributes

Big Spiders always have eight legs and numerous quills. Their bodies have slight size variation. They possess both short, knobby, black quills and long, brown-tipped quills. They have minimal color variation. Their long quills may be green or red hued, and vary in both number and length. Big Spiders quills appear darker, as their chosen color is then darkened by the region palette's black color.

In Saint's campaign, Big Spiders are coded with the {Winter} tag. This tag changed their coloration from black to a dull, light grey. Their quills also appear lighter.


  • Big Spiders were added in the 1.5 update.
  • In Arena mode, Big Spiders are significantly more aggressive, with a shorter initial fear timer and ShyFromLight cycle.
    • Due to their bites having a high stunbonus, their grabs are effectively 100% lethal in Arena.
  • Big Spiders regenerate health at a rate of 5.89% per second.
  • Their fangs are completely visible when bared even in complete darkness, making it easier to know when they are about to strike.
  • Like other Slugcat-sized creatures, Big Spiders' corpses can boost the player's speed in tunnels when held.
  • If licked by ✔️DLC Saint, Big Spiders immediately see them and no longer stay away from them.
