Wandering Spider
From WikiRaider
Wandering Spiders are the source for the Dart Poison that Lara Croft needs for Crafting Fear Arrows. It is highly hallucinogenic and makes her Enemies shoot each other in blind rage before they succumb to the poison themselves.
The poison from these arachnids can be used for crafting hallucinogenic Fear Arrows.
On-screen Info
Wandering spiders are not as common as other animals in the Peruvian Jungle. They can mostly be found in dark places like caves, Crypts and underground Tombs.
