Zell's Limit Break: Duel When Zell's limit is activated, a small window will appear at the bottom of the screen. This window shows all the available moves you can perform. To the right of the window, is the timer for your combo. If you do not enter a combo in the set time, the attack will end. When you correctly enter a combo, the window will disappear, then reappear with a new set of combos. Sometimes you might notice a blank spot in the window. When these appear, you can perform Punch Rush, instead of another move. Doing the combo's might seem difficult at first, but once you know them it is a breeze.

Once I got ahold of the Strategy Guide for Final Fantasy VIII, I discovered there is no randomness to the combo's. In the tables below is the string of combos needed to perform a final attack. I have tested each string to make sure they work.
*NOTE* The string attacks were redone, using Baradygames© Official Strategy Guide as a reference.

Burning Rave

Meteor Barret
