Leap (とびこむ, Tobikomu?) is a recurring ability in the series. It has no recurring effect however.
Leap is a special command, available for Gau on the Veldt where he can learn new Rages. Once an enemy formation is encountered (it does not have to be defeated), it will show up on the Veldt where Gau can then use Leap on them, causing him to leave the party and the battle will end. When the player keeps fighting enemies on the Veldt without Gau, he will eventually return to the party at the end of a victorious battle with new Rages learned.
Gau cannot leap if he's the only member in the party, or if all other characters are considered defeated (KO, Petrify, and/or Zombie). Gau holds the sixth slot in a monster formation. There are quite a few monster formations that use this sixth slot, effectively preventing Gau from reappearing before the party in that battle. If these conditions are met, Gau has a 5/8 chance of appearing when the last monster has been defeated.
When Gau leaps, he will obtain all the Rages he didn't know yet from that particular monster formation, as well as from the formation where he returns. If Gau is harmed by the party when he is returning, he will run away, and will not learn the Rages of the monster formation where he reappeared in (current battle). Gau will only reappear if there are three or fewer members in the party. He will not appear if the battle was a back attack, side attack, or pincer attack.
Leap is a very fast and difficult to anticipate attack used by Crimson Hound and Guard Hound.
Leap is a Green Magick ability to the Green Mage class. It increases the target's Move and Jump capabilities by 1. It can be learned for 400 AP from the Mandragora weapon and costs 18 MP to cast. It has a range of 4 tiles.
