Starting a fire is often uncertain, but one time per battle a player controlled party can start a fire without fail. Choose Attack, Fire, the direction, and then press the Start button. This will start a fire even on the castle. This DOES NOT work if it is raining and can be extinguished by rain before any harm is done, so choose a good day for a surefire fire. If a player controls both parties in the battle then each party gets one surefire fire.
