Conversion is the changing of a Piece's faction/color to another faction/colour. Conversion can be elicited by the Pieces in neighbouring spaces. Instead of attacking, the Piece chooses to Convert its neighbour. Both Pieces are immobile for the next two turns, but can still be killed, which ceases the Conversion. If a faction's King is Converted, the game ends and this faction loses.
To undertake a Conversion, the player must use their paint supplies.
