Castling is a special move in chess that involves both the king and rook chess pieces. The clues show that one must shift powers, and the puzzle is related to chess pieces; as such, the powers that shift are chess powers, specifically swapping between the king and rook pieces.
As such, by solving the chess puzzle while having Banner of the King and then choosing Resilience of the Rook as the power to switch to, all of the stated requirements have been met.
- It also works by starting with Resilience of the Rook and then swapping to Banner of the King. The emulated rook power from Ambition of the Pawn does not count.
When the puzzle is solved, the rook and king permanently swap places in The Precipice and the bishop vanishes permanently (preventing ever choosing Piety of the Bishop as a chess power after this point), being replaced with the entrance to The Precipice/Unknown.
