Certain abilities have a hidden stat called Rise. This stat causes the enemy to be propelled into the air. The most common ability is Launch, which modifies the Commando's basic Attack ability. The -ga spells (such as Firega) of Commandos and Ravagers also have the capability to Launch foes.
The value of the Rise stat determines how high the enemy will be Launched and can be combined with multiple other abilities. Once an enemy has been Launched, you can continue using -ga spells to hoist them even higher into the air, preventing them from falling back down to the ground. Any other attacks given to the enemy will also keep them airborne. Enemies that are Launched become immobilized, and cannot attack or defend themselves.
For Launching to work, generally, the attack used must have a higher Cut value than whatever Keep value the enemy has.
Many enemies cannot be Launched until Staggered while some are completely immune to Launch, Staggered or not.
