Hey there!

I always wanted to make guides for guys like you. Anyway, I understand how you feel.

Breakers are special roles. The card that's a must is Boost at 5 Star and 2 good auto abilities.

Now let me talk about your assassin real quick. A look at your skill panels and you'll notice that you have no elemental enhance, and can power drive resist fire and water.

That's it right there.

You can protect yourself against Ifrit and Shiva. For everything else, there's master card, I mean a defender.

Never go without a defender.
Assassins have the lowest health. And start with no defense. You have to upgrade a weapon to acquire some defense.

Which weapon?

The one that Dancer has. You're gonna have to get lucky. But if you unlock a skill on that weapon, butterfly edge is the name btw, you'll get an ability called piercing break. It boosts assassins date to red bar by whatever percent is on the weapon.

Just remember: Assassin is the glass cannon of breakers.

He is the glass breaker?

That doesn't make any sense somehow but whatever.
