Intended for characters with vampiric lineage. On occasion, vampires develop strange quirks that are relatively unique compared to the standard vampire powers.

If the vampire isn't in sunlight or running water, it can use its action to polymorph into a bat-humanoid hybrid of it's original size, or into a swarm of bats. The statistics for the hybrid form remain unchanged from vampire's base statistics. While in hybrid form the vampire can only use unarmed strikes and bite attacks. The statistics from the swarm are the standard stats for swarm of bats but it's maximum hit points cannot exceed the vampire's maximum hit points.. Both forms have a fly speed equal to the vampire's walking speed (minimum 30 feet). Any equipment it is wearing or carrying melds in the bat forms. If reduced to 0 hit points, the vampire reverts to it's humanoid form.
