I like it seems well thought out and the abilities are interesting however the 4th ability seems like it would hav major animation issues because what if there's like 30 enemies in close proximity to each other each one getting their own glass sphere seems like that would cause a issue. How about instead all enemies in a certain radius are engulfed in one bigger glass sphere.
Edit: Actually now that I think about it this move is actually similar to Oberon's ultimate so it should work sorry.
