Captive Umber Hulk

Confusing Gaze. When a creature starts its turn within 30 feet of the umber hulk and is able to see the umber hulk’s eyes, the umber hulk can magically force it to make a DC 15 Charisma saving throw, unless the umber hulk is incapacitated.

On a failed saving throw, the creature can’t take reactions until the start of its next turn and rolls a d8 to determine what it does during that turn. On a 1 to 4, the creature does nothing. On a 5 or 6, the creature takes no action but uses all its movement to move in a random direction. On a 7 or 8, the creature makes one melee attack against a random creature, or it does nothing if no creature is within reach.

Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it can’t see the umber hulk until the start of its next turn, when it can avert its eyes again. If the creature looks at the umber hulk in the meantime, it must immediately make the save.

Tunneler. The umber hulk can burrow through solid rock at half its burrowing speed and leaves a 5 foot-wide, 8-foot-high tunnel in its wake.

Bred to Serve. The umber hulk can hear and follows the commands of its Neogi master as if under the effects of dominate monster. It is friendly to all other Neogi as if under the effect of charm monster. These effects are not magical, and the umber hulk returns to this state after the effects of any magical charm effect or enchantment ends.

Multiattack. The umber hulk makes three attacks: two with its claws and one with its mandibles.

Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) slashing damage.

Mandibles. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) slashing damage.

Protection. When a creature within 5ft is the target of an attack roll, the umber hulk can use its reaction to become the target instead.
