Building an Effective Squad
The first step to dominating missions is to prepare your main team and make sure their skills complement each other. Typically, you’d want to have a short or mid range attacker, a long range sniper, and a support character. You definitely don’t want to get caught in a situation with tons of sniping enemies in high places with a team of melee experts.
Some good squad combinations include Ace/Cater/Queen, Seven/Trey/Deuce, or even Machina/Queen/Rem. Note that each of these examples consist of at least one dedicated healer or support character that can always restore your HP if you get in trouble.
Getting good in combat also means that you’ll have to switch between your characters whenever the need arises. The AI in Final Fantasy Type-0 HD is fairly competent so you don’t have to worry about your teammates wasting MP on the wrong attacks or enemies. But it’s always a good idea to swap back and forth regularly so you can farm Phantoma with each character and eliminate enemies efficiently.
