Big Spider

Wolf Spiders (called Big Spiders in game files, also referred to as Porcupine Spiders) are spider-like creatures, with many hairy protrusions on their back. They have multiple legs, along with two retractable fangs. They are aggressive and make lunges to catch slugcat. They can climb any foreground surface, but not backgrounds.Not to be confused with Spiders or Spitter Spiders.

Appearance
Wolf Spiders look like a porcupine crossed with an arachnid. They are black in appearance, have six legs used for walking and two green-yellow fangs used for lunging attacks.

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. Their lunge has a windup which makes a rustling sound, and their fangs will 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.

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 can also be used to lure others.

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.
