WotLK Glyph of growl?

[ferfy]

There's a glyph to increase chance of growl to work succesfully, but in my spell book, i don't see "growl" anywhere....

I only see challenging roar and demoralizing roar

Growl is taught along with Bear Form. If you don't have Bear Form, you have to do the questline that ends with the quest Body and Heart.
