Celestial Spider

Spider Climb. The celestial 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 celestial spider ignores movement restrictions caused by webbing.

Magic Resistance. The celestial spider has advantage on all saving throws against spells.

Magic Weapons. The celestial spider's attacks are considered magical.

Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit: 15 (2d10 + 5) piercing damage, and the target must make a DC 15 Constitution saving throw, taking 15 (3d10) 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.

Web (Recharge 5–6). a mass of thick, sticky webbing at a point of celestial spider's choice within 60 ft, the webs fill a 20-foot cube from that point. The webs are difficult terrain and lightly obscure their area. Webs layered over a flat surface have a depth of 5 feet.

Each creature that starts its turn in the webs or that enters them during its turn must make a DC 16 Dexterity saving throw. On a failed save, the creature is restrained as long as it remains in the webs or until it breaks free.

A creature restrained by the webs can use its action to make a DC 16 Strength saving throw. If it succeeds, it is no longer restrained.

The webs are flammable. Any 5-foot cube of webs exposed to fire burns away in 1 round, dealing 2d4 fire damage to any creature that starts its turn in the fire.
