Big Spider

Wolf Spiders (called Big Spiders in game files, also known as Porcupine Spiders or Porcuspiders) are spider-like creatures, with many spiny protrusions on their back. They have multiple legs, along with two retractable fangs. They are aggressive and make lunges to catch their prey. They can climb any foreground surface, but nothing on the background.

Appearance
Wolf Spiders look like a porcupine crossed with an arachnid. These creatures have a black body with six legs and various spines dangling from their bodies. The two fangs and the longest spines of the Wolf Spider have a green-yellow coloration. Wolf Spiders can be confused with Spitter Spiders or groups of Spiders in the dark regions of the world, as their green-yellow features become invisible.

Behavior
Wolf Spider aggression depends on difficulty, usually ignoring Monk completely, and avoiding direct confrontation with all slugcats. They rarely approach on the ground unless pursuing, preferring to crawl above on ceilings and walls, then dropping and lunging. It is possible to precipitate a Wolf Spider attack, as their lunge has a windup which makes a rustling sound, and their fangs display when actively hunting. Multiple Wolf Spiders hunt as a pack, and can grab and slow down slugcat upon contact, giving other spiders a slower target to aim at.



Revival
If not actively pursuing slugcat, Wolf Spiders will approach and  bite  other Wolf Spider corpses, temporarily reviving them. After a short amount of time (sub 20 seconds) the revived spider will twitch and die again, unless re-revived. Revived spiders will often seek to return to their dens to heal for future cycles. Wolf Spiders can also revive Spitter Spiders, which takes slightly longer. Depending on the attack that killed it, other Wolf Spiders take more time to revive their fallen brethren. To permanently kill them, you must use Smoke Bombs or Flashbangs.

Evasion
Wolf Spiders are adept at jumping to avoid spears, so the best time to throw is mid lunge windup. They can move quickly in tunnels, so be sure to stay in the open. Jumping over lunges is a good way to survive in close quarters. Corpses of prey or even other Wolf Spiders can also be used to lure them away.

Being grabbed by a Wolf Spider is not harmful (unlike lunges), but will slow slugcat down and allow other spiders to catch up/attack more effectively.
