Spider

Spiders are aggressive Monsters that live in Spider Dens. They are generally nocturnal; only coming out in daylight if their den is attacked. Spiders are generally found wandering alone but will join together if one of them is attacked. When killed Spiders drop Monster Meat or Silk; a valuable resource used in many crafting recipes. Spiders take two blasts from the Ice Staff to be frozen.

Behavior
Spiders caught outside during the day (such as if their Den was destroyed or they got stuck before reaching it)  will fall asleep. Those spawned from a Spider Queen however will not sleep. At dusk Spiders leave their den and roam around looking for food. They will eat any meats on the ground including Monster Meat from previously killed Spiders. If left alone they will return to their den at dawn.

Spiders who get too close to a bright light source such as a Campfire will often be frightened and retreat, however they can walk right up to fires and will do so if there is food for them. They will also chase the player close the the fire if angered.

Hunting
Spiders found wandering at night can easily be killed with melee weapons. When hit, Spiders will be stunlocked and unable to attack for a few moments, during which they can be hit again. After the first Spider is hit once other nearby Spiders will defend it. If they are far enough apart each Spider can be quickly killed before the others are in range. If Wilson is being chased by multiple Spiders close together he can kite them. This involves striking a Spider and then running out of range before other Spiders can attack. Over time each Spider will be hit multiple times and killed.

Spiders can also be caught in small animal Traps. When placed on the ground Traps can be baited with any meat to lure in a Spider. Alternatively, Spiders can be lead into unbaited traps once they start chasing. One way to clear a Spider Den is to place several Traps and lead the Spiders (and Warriors) into them after attacking the den to stir them up.

At night most Spiders will leave their dens. Larger dens however contain many Spiders and only a few leave at a time. When one of these Spiders is killed another Spider will emerge to take it's place. Killing these Spiders as they leave will slowly empty the den and allow it to be destroyed without fear of more Spiders emerging. Emptying a den in this manner will also prevent the spawning of Warrior Spiders (who will spawn if the den is attacked before it is empty).

Trivia
