The ring execution Is something similar to that of the Shadow Hearts series. If you've never seen/heard of/played Shadow Hearts 1, 2 or 3, here is a video to help you get the gist of it:
Shadow Hearts 1: Random BattleThe main character's ring execution is different, in that it is something a bit more complicated. An individual Spirit Attack will have a different ring setup, in which there are different areas to match. The main character's first move, no matter what class you choose, will always be the setup in the following illustration:
The area pointed out above is the Match Area. When the execution appears on-screen, you initiate it using the confirm button. This will send a marker around the ring. The marker is simply a line that circles the ring. Inside of the match area, you'll need to press the confirmation button once. If it is pressed outside of a Match Area or more then once within a Match Area, the skill will fail, and your turn will be forfeited.
After confirming the marker within the Match Area, the marker will circle the ring, coming back around. When the marker arrives once again to the Match Area, press the confirmation button again to confirm the skill. If the marker is confirmed over the same spot in which you confirmed it the first time, your skill will have full effect. If not, the skill will have -20% effect.
This is an example as best as I could animate it, using black and white:
And here are two examples of missing:
In ring with multiple Match Areas, there will never be more then three. You'll have to execute this same maneuver said amount of times over, for each Match Area. The same rules still apply.
