It depends of the size of the ice. If it's really big the fire would extinguish before it melds the ice. If the Piece of ice is small it would just meld.
Fire: Advantages: -scorching heat -can easily burn things Disadvantages: -if it has nothing to burn it dies -cannot increase if surrounded by ice -gets weaker with every second that passes
Ice: Advantages: -after melting it turns to water -limits the fire's area -may regenerate Disadvantages: -no movement -every fire contact creates vapours that reduce quantity
Fire has 2+ and 3-, and ice has 3+ and 2-, so ice is the best!!!!!!!!!!!!!!!!!!!!!!!
