[v0.5.7] Air Bender

Hi, 

I just wanted to clarify the last changes to Air Bender Skill. 

I missed a few updates. And I see that the skill on level 1 is not getting any effect except the sound... 
Previously, it was base jump + Air Bender jump. And now it replaces the base jump with the sound of the Air Bender.

Was the change intentional?
