Spriggans are encountered in quite a few locations in both Castle A and Castle B. They resemble tall knights that move around by hopping. When they engage an opponent, they attack by performing long sliding kicks along the floor.
The Spriggan has quite a peculiar design. First and foremost, he has no arms. His helmet does not seem to have any defined features. He wears a blue kilt boasting some sort of symbol on it. And most prominently, a gush of blue energy spreads out from his back, possibly propelling him to provide mobility.
