Conquer earth and water tribes with Prince Zuko by the fire nation barge. Just choose the village you want to attack and then gear up yourself for battle. The villagers are harder to conquer if their defenses are high. Save shipwrecked firebenders strewn out of the waters to form your crew. Use their bending energy to throw fireballs to enemy's walls. Watch out for golems and sea dragons too and collect necessary power-ups.
