Reaving Wind - Blue Magic Learning

[Areya]

Yep, another update, another spell I need help with.

In this case it's the level 90 spell Reaving Wind, which has the unfortunate distinction of coming from Amphipteres, the flying drakes that populate the past northlands.  To say the least, they don't mess around.  So any help would be appreciated.

Side note:  I wouldn't be surprised if Yovras taught a spell later....
