You can get abilities such as Combo Boost, HP Boost and Last chance by going through Command Fusion. This is done by combining two commands and adding a item which will give the command an ability to learn. For example, if you combine Cura and Cura, and also add a Rise Crystal, the result will be a Curaga command with the ability 'Air Combo Boost'. When you then master this Curaga command the ability 'Air Combo Boost' will still be available even if you unequip the command.
