Mirra is a girl who is Mongol and controls glass
First ability is a glass wall that is like a fusion of vyse and sage wall where there needs to be a wall but is an instant trigger and this is optional but she can throw the wall thing if needed and if it breaks it can be like vyse thorns.
Second ability is a glass shield that surrounds her she can't shoot nor can she be shot at but the bullets will ricochet off.
Third ability is mirrors (can have 2) and she and everyone can look at the mirror and see what's there
Ult. As big as vyse ult. (Or at most a site) Turns everything into glass able to see through and if enemies were there they will become fragile (no shield)
I'll post art of her soon but here are what the abilities look like (I tried i swear)
