Ragnara Kolbjorn's review: 
[list]
[*]Bladewind: This would take three turns to accomplish at least. The first turn you shatter it, the second you fire it, the third it strikes them. Then I suppose it would fit under grapple rules. If the opponent can break out of it, then it would be nullified.[/*]
[*]Shatter: I actually think that this should be buffed up a bit, make it once per fight. As it is a useful stunning ability, deafening your opponent for a period of time would be very useful. The once per day would obviously limit you, as time is up to the player. And if nobody progresses the day, then this power would never be able to be used again.[/*]
[*]Psychic Protection: This would take at least one turn of prep, so it can't be an instant: "I have armor now."[/*][/list]

As long as those are followed I think that Ragnara should be good to go.
