In a campaign I've been playing we recently stumbled upon a town (population of a couple of thousand) that was hidden via a large scale illusion spell, and shielded from the outside world, via a large Antimagic Field.
We were told by some of the populace that a friendly Vampire lived in town.
Which got me thinking, what are the capabilities of a Vampire living within an Antimagic Field?
Some are obvious, it cannot use its Children of the Night or Charm actions, as they are explicitly stated as magic.
But can it use Shapechanger or Spider Climb? Are the Vampire Weaknesses applicable in an Antimagic Field? Does it regenerate in an Antimagic Field?
Are these pretty much all up to the DM?
