Halo's Skilltree Wallpaper 01

I think for the blue orb, the top dots are Flight Assist and the bottom dots are Terrestrial Speed, branching off into Celestial Speed, aka Warp Speed. Since the flight orb cancels vertigo, and increasing the bottom increases her speed by a fair margin,  I think that the others will assist her in flying as well. Better reflexes or sharper sight or Spidy Sense for things coming at her.
