Spiders, sometimes referred to by fans as Coalescipedes, are swarming creatures that resemble real-life spiders. Spiders are located exclusively within the darkest areas of Shaded Citadel. These normally non-hostile creatures are afraid of light and will flee from it, including light produced or carried by something, for example Lantern Mice, Scavengers carrying lanterns, or a Slugcat carrying a lantern or producing light after eating a neuron fly. However, large numbers of the spiders can aggregate, making them less fearful of light and consequently more hostile. Small clumps are harmless, but medium sized groups can potentially be dangerous to the Slugcat and Lantern Mice if they become brave enough to withstand the light. Large aggregations of these creatures coalesce into a centipede-like creature which is brave enough to bypass large light sources much quicker, so avoiding swarms is advised.

Strategy
Spiders can be broken up by throwing items at them (e.g. spears or rocks), killing a few of those directly hit and causing the rest to disperse back to individual, small spiders and thus reducing their hostility. The intense light generated from throwing a flashbang will kill all spiders in a single room.

Trivia

 * In areas where spiders are often present, a low ambient droning sound will play, alerting you to their presence and the potential danger in the room.
 * Scavengers in the Shaded Citadel have lanterns with them. This appears to indicate that they are aware that spiders fear bright light, or they're simply unable to see in the oppressive darkness of the citadel. Trading for these lanterns is the only way to acquire them, outside of stealing, murdering, or looting a corpse.
