Astral Saw Horror

Unusual nature. The horror doesn’t require food or drink, and does not breathe.

Grappler. The horror has advantage on attack rolls against any creature grappled by it.

Aerial Sweeper. If the horror flies at least 10 feet and makes a buzzsaw attack and no other attacks, it can then move up to half its fly speed away without provoking an attack of opportunity.
