Make sure to envelop as many enemies as possible at once. When you have attacks you can use the group up clusters of enemies at once, it's a good idea to go ahead and use them to do as much damage as possible at once. You can incorporate attacks known as "pincer attacks" as well, which means all enemies will suffer the same amount of damage and will clear your grid a lot faster.
Take out support magic users before other enemies. If you're facing magic users who have the capability of puttng your party to sleep or are healing each other, make sure you eliminate them first to save yourself a lot of headaches later on. They usually don't have a lot of HP to worry about anyway, so it's simple enough to take them out quickly.
Aim for combos and chain attacks together for maximum damage. Make sure you involve as many allies as possible for your attacks and chain their attacks together for an explosive offensive that will send your enemies scattering and running in the opposite direction.
Become a master at rearranging your heroes. In Terra Battle, you can actually move your heroes across different tiles by pushing them with other warriors. You can do this to strategically arrange your warriors on specific tiles that will eventually allow you to make multiple moves with minimal effort. This way, you can simply accomplish more each turn without having to split up moves across your turns.
Make sure you visit all of the Hunting Zones you can for cool loot. Hunting Zones are chock full of different equipment and types of rewards that you can walk away with, and most importantly you can find important items there that you can use to unlock additional jobs for your characters there. It's worth a look, and they change on a daily basis.
