Lilian's abilities were centered around the Phoenix Flames, a special form of fire elemental laws and because of that, she felt that there wasn't a need for a weapon. Her own body was her weapon, that's why just as she extended her arms towards First Shadow and it was akin to pointing a gun at her direction.
"Conflagration!"
Fwoosh!
From Lilian's palms, an ocean of flames surged forwards, burning the whole sky and the high temperatures reached First Shadow in a few seconds of time.
A wall of darkness appeared in front of her, blocking the path of those consecutive waves of flames and isolating First Shadow's body from the heat as well. However, she suddenly felt a single wall wouldn't last long enough and had to create another one.
