Strongest Shoot-Lock for each character:
To unlock the strongest Shoot-Lock with any character, you must complete the level 20 battle arena called “Arena’s Ruler”. The Shoot-lock will be available in your inventory afterwards.
Mastering D-links:
To level D-links, you must first use it and kill enemies until a star-shaped item is dropped. Two of these are required to completely master a D-link.
Gaining abilities:
Abilities such as Last chance, Combo Boost and HP Boost can be obtained through Command Fusion. You must combine two commands and add 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”. Once you master this Curaga command, the ability “Air Combo Boost” will still be available even if you unequip the command.
