Bend gravity around yourself, slowing your descent for 3 seconds.
It's this totally random tiny utility (on a class that gets very very little) at a pretty high level. But I've never seen anyone bring it up (not a single hit when I searched the Discord for a mention of it), nor did the Deep Dive mention it.
For those that have managed to get high enough level to use it: Is it instant-cast? Can you use it in mid-air to save from fall damage? Can it allow you to take some significant shortcuts or drift over something no other class can manage? I'd love to hear any experiences with it or use cases for it since it is, I believe, the only non-combat utility ability Spellblades have besides Gate at 51, and something I believe no other class gets anything similar.
