And here is an explanation of her main magical specialization

Jennifer utilizes an ancient form of magic known as Shadowmancy. It is highly specialized, taking the shadows themselves and turning them into a malleable substance which responds to her will power. This matter can be changed into three major states, just like water. 

Smoke: By taking the shadows and converting them into a gas, Jennifer creates a potent gaseous form that can be manipulated in multiple ways. It is poisonous to breathe and can be made corrosive if she so wishes.
Oil: Taking the shadows and turning them into a liquid state, Jennifer creates a dangerous liquid which can cause terrible damage. It is slippery or adhesive by her will, and can be ignited and set on fire.
Obsidian: Jennifer converts the shadows into a solid substance, which hold its own power apart from the others. This stone like material can be both incredibly durable or brittle by her command, and can explode with powerful force.
Once her influence has been exerted upon shadow it cannot be dispelled by light. Only by severing her influence will it revert back to normal shadow. Jennifer cannot exert influence upon shadow in total darkness.
