CR for a Battle Master Vampire?

Basically what it says in the title. Wondering what the adjusted CR would be for a vampire able to use combat maneuvers as a 10th level Battlemaster.

That depends on all it can do, does it still have everything else a vampire typically has? Is it based off the standard Vampire statblock or the Vampire Warrior statblock?

Depending on exactly what you give it and what it already has it could be anything from an 8 to an 18 but it's hard to gauge exactly what without more information.

It depends on what maneuvers you stack them with. Add a +6 to damage (some of the maneuvers add a d10, so that's the average) and calculate from there - maybe add one level to the CR but really it's negligible.

If your Battle Master vampire has sweeping attack, it's around 1.5 x average damage/ round. Even at that you're looking at a CR of about 14.

It would be using the Warrior statblock. Probably going to have Sweeping Attack, Parry, Trip Attack, Precision Attack, Disarming Attack, Maneuvering Attack, and Riposte.

Taking only what the CR calculator understands that would make it a CR 16 monster. It could be easier or tougher than that depending on how well it uses the maneuvers though.
