The Countess of Blood that was the model for the vampire Carmilla... was demonized by the skill, "Innocent Monster"... and had the Halloween trait slapped on her when she picked the Holy Grail up by chance. It's getting all too incomprehensible now.
While admiring idol culture, she has even added the trait of being a princess dreaming in the castle, piling up more attributes as a Servant.
Perhaps there was meaning in the Bathory family crest being that of a dragon, for Elizabeth is in atavistic possession of the draconic element, and becoming a Servant has caused that element to surface.
Although she looks like a devil that has come for Halloween, those horns and tail are draconic in nature. Her protruding tooth is not a vampire's fang, but a dragon's.
Rank: E- Type: Anti-Unit Noble Phantasm
(Bathory Halloween Erzsebet)
A Noble Phantasm where Elizabeth summons the castle that she had ruled her whole life - Prison Castle Csejte - and turns it into a stage to make her stand out.
Although there are some changes to the name, the contents haven't particularly changed.
Tossing aside the stories of piercing implements of torture and iron maidens while saying "that has nothing to do with me at all", Elizabeth has traded her spear for a fork as her weapon.
Because there is an overflowing amount of magical energy, she can use offensive magecraft even without having learned any magecraft. She doesn't understand it herself at all.
It is very much like Elizabeth to have an abundant secret talent yet to have no idea whatsoever how to use it.
Elizabeth Bathory (Halloween) was the first Servant available in an event shop, and the first Servant to not require standard Ascension Items for ascension.
