Forest Dweller

"ELEMENT ONE! FIRE!" Venach screams, glowing and flying around the battlefield. You realize that you are trapped- walls of fire reaching higher than your eye can see block any escape. He gains speed until your eyes can no longer keep up. Something tells you this is no ordinary fire that covers his body. Ayla certainly got some of her skills from her father. Even if the scumbag raped her mother. You prepare yourself. Soon countless lines of fire surround you. Venach is somewhere in there. You decide water or ice would be best to combat this. Water would put out a normal fire, but if this is a special fire it could leave you screwed. Ice, on the other hand, would allow you to his presence if he melted through it... perhaps long enough to get in a good strike. However, by the time he melts through the ice it could be too late.
Or you could try matching fire with fire. Something tells you you only have one chance at this.
