I believe you are underselling the effect of "No Negative Status Effect" at 4 seconds with 90 MP. Perhaps crank it down a little and bump the MP cost up. The cloak is... truly unique, almost like a white bag. Also, perhaps bump the speedy down. 5 seconds on a 75 speed class is bonkers. Cooldown for how long?
Edit: Auvum means age in latin, Augustic means... of August properties? Perhaps some explanation is due.
