How do you

[WolfofLight]

Get the Werewolf armor/equipment or vampire armor/equipment?

 

[Kasimir]

Become a Werewolf/vampire.

Spoiler

Vampire: 24 AGI, Ironflesh 4, Vampire Blood.
Werewolf: 24 STR, (Shield?) 4, Werewolf Blood.

Vampires and werewolves appear around level 20.

And with that,

talk to the Bloodfountain, ask about the Dark Legends of Calradia, ask about the Curses of Sun and Moon (I believe), choose either Werewolf or Vampire.
