Item description:

When Terra is opening the Sealed Gate and your party has to face Kefka to buy time, Kefka has a chance of using a special attack. The problem is, it’s not really that special. It’s so not-special that it always misses. It’s so not-special that it has no animation. In fact, it’s so not-special that it apparently doesn’t even have a name. So when he uses it, all you’ll see at the top of the screen is a blank window. This patch causes Special attacks used by characters to load correctly so this doesn’t happen.
