Ungol Spider

Uncanny Shift. As a bonus action, the spider can move up to half its movement speed without provoking an opportunity attack.

Hit: 20 (4d8 + 4) piercing damage, and the target must make a DC 17 Constitution saving throw, taking 20 (5d8) 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: +8 to hit, reach 10 ft. Hit: 12 (2d8 + 4) slashing damage. The target must succeed on a DC 17 Dexterity saving throw or be grappled (escape DC 17). Only one creature at a time can be grappled by the spider.

Venom Spray. Ranged Weapon Attack: +9 to hit, range 30/60 ft., one creature Hit: 20 (5d8) poison damage, and the target must make a DC 17 Constitution save or be blinded until the end of their next turn.

Web (Recharge 4–6). Ranged Weapon Attack: +9 to hit, range 60/90 ft., one creature. Hit: The target is restrained by webbing. As an action, the restrained target can make a DC 17 Strength check, bursting the webbing on a success. The webbing can also be attacked and destroyed (AC 12; hp 25; vulnerability to fire damage; immunity to bludgeoning, poison, and psychic damage).

Sting. A grappled or restrained creature can be stung. The spider can use its bonus action prior to the attack as part of the trigger. Melee Weapon Attack: +9 to hit, reach 5 ft., one creature. Hit: 13 (2d8 + 5) piercing damage. If stung, the target is poisoned for 1 hour and must make a DC 17 Constitution saving throw, taking 20 (5d8) poison damage on a failed save, or half as much damage on a successful one. For 1 minute, the creature must repeat the saving throw at the beginning of each of its turns while poisoned. On a successful save, the target takes no additional poison damage on that turn. On a failed save, the target takes 8 (2d8) poison damage and is paralyzed until the end of its next turn. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for an additional hour, even after regaining hit points, and is paralyzed while poisoned in this way.
