Auto-Cast Arcane Eye on Self

[mpa]

Very useful for the frail magic users everywhere.
Your spells have awesome range but your puny eyes have been weakened from years of reading ancient dusty tomes in the archives.

As of the moment I am using AutoHotkey macro to cast it on me. But that still requires me to press the hotkey button everytime the spell expires.
Since it does not take any turn to cast the thing, it'd be an awesome candidate for auto cast.
