This must be...

The sword is light. 

My body became lighter.

I use the dead body of the giant creature as a point of jump to take me higher in the air. I scratch all three of them. One in the arm, the other on the face. Last is the tail. 

Scratch. That's all I inflect. And the white flame from my sword burns right from the wound. The creatures howled in pain. As the fire grew larger, it consumes their body parts. Until they cease to ashes. 

A smile tug on my lips. I see. I should have done this before. That Paige woman… 

I moved on to the next creature and leap at the top of its mane. The neck may be the vulnerable part… but to get an instant kill… splitting the head in half is the best. I point my sword down. My palm sliding the top of the hilt.

Thwack!
