Crystalline Beholder

Antimagic Cone: The Crystalline Beholder's central eye creates an area of antimagic, as in the antimagic field spell, in a 150-foot cone. At the start of each of its turns, the Crystalline Beholder decides which way the cone faces and whether the cone is active. The area works against its own eye rays.

Crystalline Body: The Crystalline Beholder’s body is made of dense, reflective crystal. Whenever a creature within 60 feet of the Crystalline Beholder targets it with a ranged spell attack or line spell, there is a 50% chance the spell reflects back at the caster as if it originated from the Crystalline Beholder, turning the caster into the target.

Legendary Resistance (3/Day): If the Crystalline Beholder fails a saving throw, it can choose to succeed instead.

Crystalline Regeneration: The Crystalline Beholder regains 10 hit points at the start of its turn if it has at least 1 hit point remaining.

• Bite: Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (4d6) piercing damage.

• Eye Rays: The Crystalline Beholder shoots three of the following magical eye rays at random (reroll duplicates), choosing one to three targets it can see within 120 feet of it:

1. Crystalline Disintegration Ray: The target must make a DC 17 Dexterity saving throw, taking 45 (10d8) force damage on a failed save, or half as much damage on a successful one. If this damage reduces the target to 0 hit points, its body becomes crystallized and is turned to solid crystal.

2. Petrifying Ray: The target must make a DC 17 Dexterity saving throw. On a failed save, the creature begins to turn to crystal and is restrained. It must repeat the saving throw at the end of its next turn, becoming petrified if it fails or ending the effect on a success.

3. Crystal Sleep Ray: The target must succeed on a DC 17 Wisdom saving throw or fall asleep and be petrified, taking no damage but remaining incapacitated and unaware of its surroundings for 1 minute or until it takes damage.

4. Reflective Ray: The target must make a DC 17 Charisma saving throw. On a failed save, the next spell that targets the Crystalline Beholder within the next minute is reflected back at the caster.

5. Shattering Ray: The target must make a DC 17 Constitution saving throw, taking 36 (8d8) thunder damage on a failed save, or half as much damage on a successful one. Objects that aren't being worn or carried are destroyed if the ray strikes them.

6. Crystal Bond Ray: The target must make a DC 17 Wisdom saving throw. On a failed save, the creature is bonded to the Crystalline Beholder for 1 minute. While bonded, any damage the Crystalline Beholder takes is also dealt to the bonded creature.
