High Jump causes an enemy’s TP to be reduced by a percentage proportionate to the amount of damage inflicted.
Super Jump causes the closest party member behind the Dragoon (from the point of view of the monster) to have his or her enmity reduced by half.
The recast time for the Jump, High Jump, and Super Jump job abilities will be immediately reset upon use of Spirit Surge.
Upon use, the Dragoon's maximum HP is increased by roughly 15%. Following that, the Dragoon's current HP is healed by an amount equivalent to the Wyvern's current HP.
The Wyvern's current TP is also added to the Dragoon's. With proper timing, a self-Skillchain may be performed.
The Dragoon gains a large STR boost, equal to: floor((level / 5) + 1).
The Dragoon gains a large accuracy boost (including jumps).
This was thought to be 100% but has since been disproved. See discussion
The Dragoon gains 25% job ability haste.
The Wyvern's per-hit damage is added onto the Dragoon's individual attacks.
