Clockwork Beholder

Spell Redirection Cone. The clockwork beholder’s central eye creates an area of spell redirection, in a 150-foot-cone. If a creature within the cone targets the clockwork beholder with a spell or spell attack, the beholder causes that spell to hit another creature of its choice within 60 feet of it that it can see. At the start of each of its turns, the clockwork beholder decides which way the cone faces and whether the cone is active.

Legendary Resistance (4/Day). If the clockwork beholder fails a saving throw, it can choose to succeed instead

Magic Resistance. The clockwork beholder has advantage on saving throws against spells and other magical effects.

The targeted creature must make a DC 18 Dexterity saving throw, taking 36 (8d8) fire damage on a failed save, or half as much damage on a successful one.  On a failed save, the creature catches fire; until someone takes an action to douse the fire, the creature takes 10 (2d10) fre damage at the start of each of its turns.
