The reason that Tammy looked like this was because she found that the ice breath was just too weak.
It had barely consumed the fire energy that she had tapped into from this Inferno Gem to form this barrier.
In fact, she still had plenty of energy left after stopping that ice breath.
Too much that if she didn't use it, it would actually hurt her.
So Tammy gathered more fireballs around her and shot them at the ice dragon.
This time, the ice dragon didn't just stay there to be hit by the fireballs.
Instead, the ice dragon spread its wings and prepared to fly into the sky to avoid these fireballs. Or at least that was what it had been planning to do before it suddenly realized that this wasn't possible.
That was because these fireballs were much faster than before.
It was just too fast for the ice dragon to dodge in time.
All it could do was gather a layer of frost around itself in an attempt to shield against these fireballs.
