Spider Climb. The spider can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 12 (2d8 + 3) piercing damage, and the target must make a DC 13 Constitution saving throw, taking 10 (3d6) poison damage and 7 (2d6) cold damage, or half as much 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.
Web (Recharge 5-6). Ranged Weapon Attack: +5 to hit, range 30/60 ft., one creature. Hit: The target is restrained by webbing. As an action, the restrained target can make a DC 12 Strength check, bursting the webbing on a success. The webbing can also be attacked and destroyed (AC 10; hp 10; vulnerability to fire damage; immunity to bludgeoning, poison, and psychic damage).
The frost spider is a variation of the more common giant spider found in cold locales. Its body is predominantly white with icy blue highlights.
