Corrupt Origami Spider

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 Corrupt Origami Spider makes 2 attacks. 

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 4 (2d8 + 3) 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.

Brute Force. Melee Weapon Attack: +4 to hit, reach 10ft, hit (2d10 + 3) bludgeoning damage. The spider slams down with one of its massive legs. The target must make a DC 15 STR save or be knocked prone. 

Call The Hoard: Once per day the Corrupt Origami Spider may call forth 1d4 Giant Spider's to come to its defense. 

Entangle: When attacked the Corrupt Origami spider attempts to trap the attacker in sticky webbing. The attacker must make a DC 16 DEX save or become restrained. At the end of their turn confined creatures can make a DC 13 STR save to break free of the webs. 
At the start of the Corrupt Origami Spider's turn roll 1d8 on a 4, 6, or 7 the Spider regains its Entangle reaction, on a 1, 2, 3, 5, or 8 it does not.
