Interesting concept. I think the passive needs a little change though. Destroying projectiles should be changed to non ult projectiles. Also it should cost some maximum mana when ever triggered. That itsn't say that it needs mana to use, it just takes it.

This makes destroying projectiles a bit more interesting as it can screw over your mana sustain if you manage it poorly.
