Shauri's Sonorous Clouding sometimes breaks itself by "casting" the spell instead of continuing to play. The issue is that it can randomly do that in the middle of consistant play. So it will cast, youll be invis, cast, break invis, land- youll be invis- so on and so forth.

It almost always breaks itself initially, especially if played directly after another song. ( Perhaps when the song fades it takes the invis with it )
