Spider Climb. The spider can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Web Sense. While in contact with a web, the spider knows the exact location of any other creature in contact with the same web.
Web Walker. The spider ignores movement restrictions caused by webbing.
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 1d6+1 piercing damage, and the target must make a DC 11 Constitution saving throw, taking 7 2d6 poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.
Smaller than a giant spider, a giant wolf spider hunts prey across open ground or hides in a burrow or crevice, or in a hidden cavity beneath debris.
