Dancer

Dancers are enemies added in v1.8, the Bestiary Update. They appear exclusively within the Slumbering Sanctuary.

Behavior
Dancers are only capable of stabbing towards the player repeatedly, but this attack cannot be parried. If the Beheaded attempts to do so, the Dancer will instantly end their attack, and continue to repeatedly stab once the window for the parry has ended. The dancer can also dash behind you and stab you in the back.

Strategy
It is best to roll through their first attack, and then retaliate before the Dancer has another opportunity to attack.
