DFA

A DFA, or "Death From Above" (not to be confused with a Katas or Lunges) is a special move initiated by pressing forward, jump and attack at once. They tend to restrict the player's movement, making them open to attacks, but do a large amount of damage.

Red DFA

Generally when referring to "DFA" with no further description, this is the move being referred to. The player leaps forward striking the ground with his saber dealing very high damage, usually enough to instantly kill a player.

The execution varies between JK2 and JKA.

JKA

In JKA, the move is done with the usual jump+forward+attack combo

JK2

In JK2 MP, the move is done by pressing jump during a combo. JK2 SP follows roughly the same guidelines as JKA. This results in a large forward lunge which is capable of killing a player in one hit.

Yellow DFA

Also known as YDFA, the player leaps upwards into the air in a flip, and attacks below him. This attack is notable due to the server remaining active (still dealing attack dammage) whilst it is being held still at the end of the attack. This quirk can be used to deal large amounts of damage via exploits.

In singleplayer, there are two versions of this DFA.

Staff and Dual Butterfly

With staff or dual, the same combo causes the player to begin a multiple hit combo in which they travel forwards spinning around. There is a limited amount of control over which direction the player moves in, by turning with the mouse, but the direction is locked for parts of the move.
