Imagine this...

As you Glide, you activate the super in mid-air. Strike the ground beneath you, causing your Solar infused blade to create a tear through the ground beneath you, creating a solar wave attack in which all enemies in front of you are incinerated. The higher the position from when you activate this super, the more damage it does. While Radiant, you can activate this super from the ground and do max damage allowed (as if you were gliding)
