Chaos Weaver

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.

Multiattack. The Chaos Weaver gets multiattack; one with its bite and one wit hits claws, or two with its claws.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 10 (2d8 + 3) piercing damage, and the target must make a DC 14 Constitution saving throw, taking 9 (2d8) 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.

Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 10 (2d8 +3) slashing damage. 

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 5; vulnerability to fire damage; immunity to bludgeoning, poison, and psychic damage).
