I haven't looked at the comments yet or your own but I can tell that passive is obscenely strong. It's basically a reworked Kayle passive... and that passive was the reason why she was considered one of the strongest late game champions ever. And on top of that it gives you huge percentage penetration for both forms of damage. Both aspects need serious toning down.

Also, this is probably nitpicking, but I wouldn't have the item share a recipe with Guinsoo's. It's not original.
