Judgment rules are a feature in the Dissidia series, first introduced in Dissidia Final Fantasy. They appear once the player completes all Destiny Odysseys, and manifest as Chaos and Cosmos directly influencing the battle in various ways. In custom battles, players can choose to enable Chaos Judgment, Cosmos Judgment, both Judgments, abstain from using Judgment rules, or randomize from any of the previous options.
The two rules are as follows:
When a character enters critical health their EX Gauge will be filled. When a character gains enough Bravery to kill the opponent in one hit, the opponent's summon is restored if it has been used. Both effects will only happen once to each character, but one character may benefit from both effects. In Dissidia 012, Cosmos will also shield the player's Assist Gauge from depleting when the opponent enters EX Mode.
When a character does not attack for an extended period of time, they will be paralyzed for several seconds. This can occur to a character multiple times. After the battle has lasted a period of time, the notice "Invitation to Destruction" appears. The longer the battle continues after this appears, the greater the Bravery damage inflicted by both characters increases. The odds of critical hits occurring also increase. Eventually this caps out when all attacks are critical hits and the damage they do stops increasing.
