Each of your Titans have their own targetable skills that can be filled up when you collect Skill Orbs or attack opponents. But since different skills have different effects in battle, and since some Titans specialize in healing or protecting your team, you’ll want to have a versatile army of Titans. It’s also good to save the aforementioned special skills for special attacks or more difficult opponents, and even if you have healers, you should also stock up on potions for extra healing in-battle.
When your Titans head out to battle, you’ll have four of the seven in front, and the remaining three at the back. It’s the ones in front whom you want protecting the three others in the back row, so with that in mind, your four front-liners should be the ones with the highest HP.
Of course, before you can lead an army of seven, you have to start with smaller things, and that, in this game, would be a team of only three Titans. That makes it important to unlock your extra deck slots as quickly as possible.
This essentially means having your lower-skill Titans take care of enemies who have less hit points in them, while saving your more skilled Titans for tougher, more imposing opponents.
You’ll notice that each of your Titans have Leader Skills, which would only be activated if you delegate them to be the leader of your team. This would provide special boosts to your deck of Titans, but you also should be aware of when those skills work the best. For example, high-HP opponents can be disposed of with a leader with Enrage as his Leader Skill, while faster, more evasive enemies would have trouble if your team’s got a leader with Quagmire.
We did talk about fusing your Titans, but aside from that, you can also evolve them by combining two identical Titans; this would make your evolved Titan considerably stronger. You can also fuse Titans if they’re different from each other, and this would create a completely different Titan with different – and very impressive – powers. The latter, however, would require Lyras, so be sure to save them up if you need to fuse two Titans.
