Promotion Path
Instead of moving, Players may spend XP to promote a piece.
- A piece cannot be promoted more than 1 rank in a single turn.
- A Player cannot promote while in check.
Mustering
Instead of moving, Players may spend 5 XP to muster a new Grunt onto the battlefield.
- Place the Grunt on any empty square adjecent your King.
- Players start with 14 pieces and cannot muster new units until they have less than 10 pieces.
- Mustering may be done while in check provided that your King is not in check at the end of your turn.
Other Pieces
Knight, Bishop, Rook, Queen, and King move exactly as in classical chess.
Victory
Checkmate wins the game. Stalemate is a draw.
