Press the fabled stone to your ranks and transmute base metal to gold: three of your pawns become queens, once.
You draft Philosopher's Stone in Buff mode. Activated: you choose when to use it, and using it is your move for that turn.
As a pieces card, it summons, revives, promotes, or converts a piece.
“The final work of a thousand alchemists.”
Needs one of your pawns in play.
