Baby Phase Spider (Pet)

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.

Nimbleness. The spider can move through the space of any creature that is of a size larger than it's own.

Naturally Stealthy. The spider can attempt to hide even when it is obscured only by a creature that is at least one size larger than it's own.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 4 (1d4 + 2) piercing damage, and the target must make a DC 9 Constitution saving throw, taking 2 (1d4) 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.

Ethereal Jaunt. As a bonus action, the spider can magically shift from the Material Plane to the Ethereal Plane, or vice versa.

Web (Recharge 5–6). Ranged Weapon Attack: +5 to hit, range 20/40 ft., one creature. Hit: The target is restrained by webbing. As an action, the restrained target can make a DC 10 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).
