I am not the original creator of this format. If you want to see the original post:
I just wanted to add my own ideas.
The numbers and damage type need to be adjusted, they only serve as an example.
The Item is optional as well, but creates more combinations that will improve the overall gameplay.
Classes and origins are up for change as well, but I think Xerath as Elementalist is better than sorcerer (sorcerer would be too broken).
Please let me know what you think, and share the idea.
I hope riot considers this.
