Aangs Bending

In regular combat, Aang can only send air blasts to kill enemies. However, sometimes when you are not in combat sometimes you'll need to bend and element to do something, complete something, or make something happen. Special symbols appear that indicate which element you need to use (a special symbol appears for Sokka). Aang can bend every element (excluding Sokka's boomerang, machete, and club) when it comes to these special bending moves. Be aware though that these special moves can be performed if there is anything involving the element near the fight eg. A bucket of water, a lamp, etc. Hope this provides some sufficient insight on the game.
