Up to 2 of your knights or bishops become vampires: each of their captures gains you 6 seconds, and the first time one is killed it returns 3 of your turns later on a square next to where it fell.
You draft Vampire Court in Buff mode. Free action: you choose when to use it, and it resolves without costing your turn.
As a pieces card, it summons, revives, promotes, or converts a piece.
“The court convenes at dusk and bills by the neck.”
Needs one of your knights and bishops in play.
