From D&D Wiki
large monstrosity, chaotic neutral
Intimidate. When the arbok's enemies are rolling for initiative, they have disadvantage.
Constrict. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) bludgeoning damage. The arbok wraps its body around its target and squeezes them. The creature is counted as grappled. For every turn that the creature is in the arbok's grasp, they take an additional 6 (1d8 + 2) bludgeoning damage and the arbok cannot take any actions or move while using this ability. It can, however, take an action to end the grapple, then move.
Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) piercing damage. If the target was a creature, then the creature is now poisoned.
Arbok are a large snake-like creature, standing at a little over 11 feet tall when upright. They frequently have a pattern on the undersides of their crests that are reminiscent of a face, likely to keep predators at bay, but it also helps stun prey so that they are easy pickings. Arbok don't tend to bother people, but when threatened they will attack anything in sight.
