Multiattack

The urochar can use its Paralyzing Gaze. It then makes four Tentacle attacks.

Tentacle

Melee Weapon Attack: +13 to hit, reach 20 ft., one target. Hit: 25 (4d8 + 7) bludgeoning damage, and the target is grappled (escape DC 19) if it is a Large or smaller creature. Until this grapple ends, the target is restrained. The urochar has four tentacles, each can grapple only one target.

Paralyzing Gaze

The urochar turns its eerie gaze upon one creature it can see within 60 feet of it. The target must succeed on a DC 19 Wisdom saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a target's saving throw is successful or the effect ends for it, the target is immune to the urochar's Paralyzing Gaze for the next 24 hours.

Strangling Grasp

Each creature grappled by the urochar must make a DC 19 Strength saving throw. On a failure, a creature takes 36 (8d8) bludgeoning damage and can't breathe until the grapple ends. On a success, a creature takes half the damage and can still breathe.
