Bonegazer

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

Multiattack. The Bonegazer uses Eye Rays three times.

Bite. Melee Attack Roll: +8, reach 5 feet. Hit: 13 (2d8 + 4) Piercing damage.

Eye Rays. The Bonegazer randomly shoots one of the following magical rays at a target it can see within 120 feet of itself (roll 1d10; reroll if the Bonegazer has already used that ray during this turn):

1. Charm Ray. Wisdom Saving Throw: DC 16. Failure: 13 (3d8) Psychic damage, and the target has the Charmed condition for 1 hour or until it takes damage. Success: Half damage only.
2. Paralyzing Ray. Constitution Saving Throw: DC 16. Failure: The target has the Paralyzed condition and repeats the save at the end of each of its turns, ending the effect on itself on a success. After 1 minute, it succeeds automatically.
3. Fear Ray. Wisdom Saving Throw: DC 16. Failure: 10 (3d6) Psychic damage, and the target has the Frightened condition until the end of its next turn. Success: Half damage only.
4. Slowing Ray. Constitution Saving Throw: DC 16. Failure: 18 (4d8) Necrotic damage. Until the end of the target’s next turn, the target can’t take Reactions; its Speed is halved; and it can take either an action or a Bonus Action on its turn, not both. Success: Half damage only.
5. Enervation Ray. Constitution Saving Throw: DC 16. Failure: 16 (3d10) Poison damage, and the target has the Poisoned condition until the end of its next turn. While Poisoned, the target can’t regain Hit Points. Success: Half damage only.
6. Telekinetic Ray. Strength Saving Throw: DC 16 (the target succeeds automatically if it is Gargantuan). Failure: The Bonegazer moves the target up to 30 feet in any direction. The target has the Restrained condition until the start of the Bonegazer's next turn or until the Bonegazer has the Incapacitated condition. The Bonegazer can also exert fine control on objects with this ray, such as manipulating a tool or opening a door or container.
7. Sleep Ray. Wisdom Saving Throw: DC 16 (the target succeeds automatically if it is a Construct or an Undead). Failure: The target has the Unconscious condition for 1 minute. The condition ends if the target takes damage or a creature within 5 feet of it takes an action to wake it.
8. Petrification Ray. Constitution Saving Throw: DC 16. First Failure: The target has the Restrained condition and repeats the save at the end of its next turn if it is still Restrained, ending the effect on itself on a success. Second Failure: The target has the Petrified condition instead of the Restrained condition.
9. Disintegration Ray. Dexterity Saving Throw: DC 16. Failure: 36 (8d8) Force damage. If the target is a nonmagical object or a creation of magical force, a 10-foot Cube of it disintegrates into dust. Success: Half damage. Failure or Success: If the target is a creature and this damage reduces it to 0 Hit Points, it disintegrates into dust.
10. Death Ray. Dexterity Saving Throw: DC 16. Failure: 55 (10d10) Necrotic damage. Success: Half damage. Failure or Success: The target dies if the ray reduces it to 0 Hit Points.

Negative Energy Cone. The Bonegazer's central eye emits an imperceptible, magical wave of negative energy in a 150-foot Cone. Creatures in that area can’t regain Hit Points until the start of the Bonegazer's next turn. An intact Humanoid corpse there instantly rises as a Zombie under the Bonegazer's control and takes its turn immediately after the Bonegazer on the same initiative count.

Legendary Action Uses: 3. Immediately after another creature’s turn, the Bonegazer can expend a use to take one of the following actions. The Bonegazer regains all expended uses at the start of each of its turns.

Chomp. The Bonegazer makes two Bite attacks.

Glare. The Bonegazer uses Eye Rays.
