Multiattack

The goliath longlegs makes one bite attack and then as many leg attacks as it has legs. It can use its Reel in place of two leg attacks.

Bite

Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 8 (1d8 + 4) piercing damage and the target must make a DC 15 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 hp, the target is stable but poisoned for 1 hour, even after regaining hp, and is paralyzed while poisoned in this way.

Leg

Melee Weapon Attack: +7 to hit, reach 15 ft., one target. Hit: 6 (1d4 + 4) piercing damage.

Paralytic Web (Recharge 5-6)

Ranged Weapon Attack: +5 to hit, range 30/60 ft., one Large or smaller creature. Hit: The creature is restrained by webbing and must succeed on a DC 15 Constitution saving throw or be paralyzed for 1 minute. The creature can repeat the saving throw at the end of each of its turns, ending the paralyzed effect on itself on a success. As an action, the restrained creature can make a DC 15 Strength check, escaping from the webbing on a success. The webbing can also be attacked and destroyed (AC 12; hp 15; vulnerability to fire damage; immunity to bludgeoning, poison, and psychic damage).

Reel

The goliath longlegs pulls one creature caught in its web up to 30 feet straight toward it. If the target is within 10 feet of the goliath longlegs, the goliath longlegs can make one bite attack as a bonus action.
