[Skin Concept] Dark Star Taliyah
The character design I'm not sure of, just thinking of the skills.
Basically her Q would pull up obsidian space rocks. The W would would blacken the earth and spikes would come out of the side that pushes. Her E would send out little tiny dark stars as the mines that would detonate when triggered. Finally with her R she would summon a large dark star that she that leaves behind a chasm with dark fire inside it.
